Question

Find the unknown sizes of angles ​

Answer 1

Answer:

115°=x°

65+x=180

x=180-65

x=115°

Answer 2

${\huge{\pink{\underbrace{\overbrace{\mathbb{\blue{ANSWER:-}}}}}}}$

As ΔPQR is a isosceles triangle with RP=RQ

So,

∠RQP=∠RPQ

∠RPQ=65°

We know, two angles of a triangle add up to the opposite external angle

So,

∠RQP+∠RPQ= x

65+65=x

$\huge\boxed{\red{x=130}}$
