Question

6 The interior angles of a triangle always sum to 180°. The measure of ZC is 8°

less than the measure of ZD. Find the values of x and y.

Answer 1

m<D=67

m<C=59

Explanation:

m<C=y-8

m<D=y

m<A=54

put all the angles together and equal to 180

(y-8)+(y)+(54)=180

now solve the equation

67=y

(67)-8=59
