Question

Find the missing value of x,y and z

Answer 1

x=60

y=30

z=64

Explanation:

By using triangle sum theorem, 84+36+x=180

You then isolate the variable, resulting in x=60

x and y are complementary, therefore, x+y=90

Since x is already known, y must be isolated, resulting in 60+y=90 then y=30

By using triangle sum theorem, 86+y+z=180

Since y is already known, z must be isolated, resulting in 86+30+z=180 then z=64
