Here are the solutions to your questions: 8. Triangle KLM is similar to triangle QRS where angle K corresponds to angle Q and where angles L and R are right angles. If K = (105)/(233) and M = (208)/(233), what is the value of S? Step 1: Understand similar triangles and angle relationships. Since KLM QRS, their corresponding angles are equal. This means K = Q, L = R, and M = S. We are given that L = 90^ and R = 90^. In a right-angled triangle, the sum of the two acute angles is 90^, so K + M = 90^. Step 2: Use the given sine values to find the sides of KLM. Let the sides opposite to angles K, L, M be k, l, m respectively. In KLM, L = 90^. We are given M = (208)/(233). In a right triangle, M = oppositehypotenuse = (m)/(l). So, we can assume m = 208 and l = 233 (or a multiple thereof). We are also given K = (105)/(233). In a right triangle, K = oppositehypotenuse = (k)/(l). This implies k = 105 and l = 233. These values are consistent: k=105, m=208, l=233. Step 3: Verify with the Pythagorean theorem. Check if k^2 + m^2 = l^2: 105^2 + 208^2 = 11025 + 43264 = 54289. 233^2 = 54289. The side lengths are consistent with a right triangle. Step 4: Calculate M. The tangent of angle M is M = oppositeadjacent = (m)/(k). M = (208)/(105) Step 5: Determine S. Since M = S, we have S = M. S = (208)/(105) The value of S is (208)/(105). 9. In the diagram, ABC is similar to EDC, with BAC corresponding to CED and ABC corresponding to CPE. Which of the following must be true? The options are: A) AE BD, B) AE BD, C) AB DE, D) AB DE. Step 1: Interpret the similarity statement. Given ABC EDC. This means their corresponding angles are equal: • BAC = EDC • ABC = DEC • ACB = ECD (These are vertically opposite angles, which are always equal, confirming the similarity). Step 2: Analyze the relationship between lines AB and DE. Consider lines AB and DE intersected by the transversal line BD. The angles ABC and EDC are alternate interior angles. From the similarity, we know that ABC = EDC. Step 3: Apply the property of parallel lines. If alternate interior angles formed by a transversal intersecting two lines are equal, then the two lines are parallel. Since ABC = EDC, it implies that line AB is parallel to line DE. Step 4: Select the correct option. The statement that must be true is AB DE. The correct option is C) AB DE. 10. If arc FG is congruent to arc GH and the measure of G is 30^, what is the measure of H? Step 1: Understand the properties of congruent arcs in a circle. If two arcs in a circle are congruent (arc FG arc GH), then the chords that subtend these arcs are equal in length. So, chord FG = chord GH. Step 2: Identify the type of triangle. Since chord FG = chord GH, FGH is an isosceles triangle. Step 3: Apply properties of isosceles triangles. In an isosceles triangle, the angles opposite the equal sides are equal. The angle opposite side FG is H, and the angle opposite side GH is F. Therefore, F = H. Step 4: Use the sum of angles in a triangle. The sum of the interior angles of any triangle is 180^. F + G + H = 180^ Substitute F = H and the given G = 30^: H + 30^ + H = 180^ 2 H + 30^ = 180^ Step 5: Solve for H. 2 H = 180^ - 30^ 2 H = 150^ H = (150^)/(2) H = 75^ The measure of H is 75^. 11. Triangle ABC is a right triangle and B = (5)/(13). What is the length of side BC? The diagram shows a right triangle ABC, with the right angle at C. The hypotenuse AB has a length of 26. Step 1: Use the definition of sine in a right triangle. In a right triangle, (angle) = opposite sidehypotenuse. For angle B, the opposite side is AC and the hypotenuse is AB. So, B = (AC)/(AB). Step 2: Substitute the given values and solve for AC. We are given B = (5)/(13) and AB = 26. (AC)/(26) = (5)/(13) Multiply both sides by 26: AC = (5)/(13) × 26 AC = 5 × 2 AC = 10 Step 3: Use the Pythagorean theorem to find BC. In a right triangle, AC^2 + BC^2 = AB^2. Substitute the known values AC = 10 and AB = 26: 10^2 + BC^2 = 26^2 100 + BC^2 = 676 Step 4: Solve for BC. BC^2 = 676 - 100 BC^2 = 576 BC = sqrt(576) BC = 24 The length of side BC is 24. 12. All the dimensions shown are for the interior of the triangle. What is the value of x? The diagram shows an isosceles triangle with two equal sides of 24 ft and a base of 32 ft. The base angles are labeled x. Step 1: Draw an altitude to create right triangles. Draw an altitude from the apex (the vertex between the two equal sides) to the base. In an isosceles triangle, this altitude bisects the base and forms two congruent right-angled triangles. Step 2: Determine the lengths of the sides of one right triangle. The hypotenuse of each right triangle is one of the equal sides of the isosceles triangle, which is 24 ft. The base of each right triangle is half of the isosceles triangle's base: 32 ft2 = 16 ft. The angle x is one of the acute angles in this right triangle. Step 3: Use the definition of cosine in a right triangle. In a right triangle, (angle) = adjacent sidehypotenuse. For angle x, the adjacent side is 16 ft and the hypotenuse is 24 ft. x = (16)/(24) Step 4: Simplify the fraction. x = (16 ÷ 8)/(24 ÷ 8) x = (2)/(3) The value of x is (2)/(3).
