Question

find the values of X and y in the following figures
STEP BY STEP EXPLANATION​

Answer 1

Step-by-step explanation:

1. Since opposite sides are equal in this case so x=y = (180-70 )/2= 55°

2. In this case side opposite to 50° is equal to side opposite to y=50° & x is external angle equal to 50°+50°=100

3. y is vertically opposite to 30° hence y=30° & x= 180-(30+30) = 120°

4. y = 180- 110=70° & x =180- (70+70)= 40°

5.y= 180-30= 150° & x = 180-(90+30)= 60°

6.x= (180-80)/2 = 50° & y = 180-50= 130°
