Question

please give me this answer​

Answer 1

answer x=60°

x=137°

x=116°

Answer 2

Answer:

1 ) In first triangle all the sides are equal therefore it is a equilateral triangle therefore the angle is equal to 60 degree. (x =60 °)

2) in the second triangle

A + B + C =180

A =90

B = 43

C = x

therefore

90+43+x = 180

x = 180 - 133 = 47°

3) in the third triangle

A + B + C =180

A =90

B = x

C = 64

therefore

90+x+64= 180

x = 180 - 154= 26°
