WebFeb 22, 2024 · Because of AA similarity as their corresponding angles are equal in measure. Considering ABC and QBP ,we get. B P B C = B Q A B = P Q A C = k (a constant) We get Q P = 10 k and B Q = 6 k. As all sides of a square are equal,QR will be also equal to QP i.e Q R = 10 k. Considering ABC and QBP ,we get. WebAB = 6 BC = 8 Then, we will calculate the hypotenuse AC using the formula. ==> AC^2 = BC^2 + AB^2 ==> AC^2 = 6^2 + 8^2 = 36+64 = 100 ==> AC = 10 Now we need to find the following: sinA...
