Question

find the value of X
​

Answer 1

Step-by-step explanation:

x will be 90 because in first triangle the measurements of angles are 100° ( 180-y) and (180-y)so by doing this calculation by the method 100°+ (180° - y)+(180°-y)=180°

so y = 40°

coming on next triangle angle z= 50° because of the angle sum property that i was doing in before question.

After this x=z+y

so x=50°+40°= 90°
