Question

4. Calculate the size of each lettered angle in the following figures :​

Answer 1

Step-by-step explanation:

angle =32

angle 32 =x

opposite angle of equal sides

in a ∆

32+x+a =180. ( a is a new angle which

32+32+a=180. we let in ∆of angle x )

a=180-64

a=116

a =z (alternate interior angle )

and,

a+y =180. (linear pair of angle)

116+y=180

y=180-116

y=64
