Question

sollve this please show me these parts​

Answer 1

Answer:

X = 60

U = 60.

Step-by-step explanation:

It's a Equilateral triangle.

As the outer angle is 120, The x is 180 - 120 = 60.

As the adjacent angle is also X. The remaining angle Y = 180 - 2X = 180 - 120 = 60

Answer 2

Answer:

S-Q-R

= angleSQP+anglePQR=180----(linear pair)

=120+angle PQR=180

angle PQR=180-120

angle PQR=60°

Therefore anglePRQ=60--both are equal=x)

angle P+angle Q + angle R=108---(sum of triangle)

Therefore,

angle P=60°

Therefore,

Angle Q=R=P=60°

Therefore it's an equilaterial triangle
