The sum of angle on a straight line is

Here are the solutions to the questions: 1. The sum of angle on a straight line is A straight line measures 180^. The correct option is (d) 180^. 2. The triangle which has its three sides equal is A triangle with three equal sides is called an equilateral triangle. The correct option is (a) Equilateral. 3. Using Pythagoras theorem, solve for b. Step 1: Apply the Pythagorean theorem a^2 + b^2 = c^2, where a=6 and c=10 (hypotenuse). 6^2 + b^2 = 10^2 Step 2: Calculate the squares. 36 + b^2 = 100 Step 3: Isolate b^2. b^2 = 100 - 36 b^2 = 64 Step 4: Take the square root to find b. b = sqrt(64) b = 8 The correct option is (a) b=8. 4. The sum of the three angles in a triangle is The sum of the interior angles of any triangle is always 180^. The correct option is (d) 180^. 5. Angle x and y are called ____ angles Angles x and y are on opposite sides of the transversal and between the two parallel lines. They are called alternate interior angles. The correct option is (b) alternate. 6. Sine 30^, cos 30^, tan 30^ 30^ = (1)/(2) 30^ = sqrt(3)2 30^ = (1)/(sqrt(3)) or sqrt(3)3 7. sin 60^, cos 60^, tan 60^ 60^ = sqrt(3)2 60^ = (1)/(2) 60^ = sqrt(3) 8. sin 45^, cos 45^, tan 45^ 45^ = (1)/(sqrt(2)) or sqrt(2)2 45^ = (1)/(sqrt(2)) or sqrt(2)2 45^ = 1 9. The sum of angle at a point is The sum of angles around a central point is 360^. The answer is 360^. 10. Write short notes on the followings a) Acute angle: An angle that measures less than 90^. b) Obtuse angle: An angle that measures greater than 90^ but less than 180^. c) Reflex angle: An angle that measures greater than 180^ but less than 360^. d) Right angle triangle: A triangle that contains one angle exactly equal to 90^.
