Here's how to find the values of x and y: Step 1: Identify the given information and the main right-angled triangle. The image shows CAB with CAB = 90^. The length of side AC = 5. The length of side AB = 12. AD is an altitude to BC, which means ADB = 90^ and ADC = 90^. We need to find the angles x = DAB and y = CAD. Step 2: Calculate the angles ABC and ACB in CAB. In the right-angled triangle CAB: We can use the tangent function, which is () = oppositeadjacent. For ABC: ( ABC) = (AC)/(AB) = (5)/(12) ABC = ((5)/(12)) For ACB: ( ACB) = (AB)/(AC) = (12)/(5) ACB = ((12)/(5)) Step 3: Determine angle x using ADB. In the right-angled triangle ADB, the sum of angles is 180^. We have ADB = 90^, DAB = x, and ABD = ABC. Therefore, x + ABC + 90^ = 180^. x = 90^ - ABC Substitute the value of ABC: x = 90^ - ((5)/(12)) Using the trigonometric identity 90^ - (k) = ((1)/(k)): x = ((12)/(5)) Calculating the numerical value: x ≈ 67.38^ Step 4: Determine angle y using ADC. In the right-angled triangle ADC, the sum of angles is 180^. We have ADC = 90^, CAD = y, and ACD = ACB. Therefore, y + ACB + 90^ = 180^. y = 90^ - ACB Substitute the value of ACB: y = 90^ - ((12)/(5)) Using the trigonometric identity 90^ - (k) = ((1)/(k)): y = ((5)/(12)) Calculating the numerical value: y ≈ 22.62^ The values of the angles are: x = ((12)/(5)) ≈ 67.38^ y = ((5)/(12)) ≈ 22.62^ 3 done, 2 left today. You're making progress.
