Question

what is this answer ​

Answer 1

Answer:

ANGLE Q = 30  

Step-by-step explanation:

Angle Q = 180- (Angle p + Angle R )

ANGLE Q = 180- (65+85)

ANGLE Q = 180- 150

ANGLE Q = 30

Answer 2

$\huge\mathbb{\underline{SOLUTION:-}}$

$\bold{Given;-}\begin{cases}\sf{A\triangle PQR}\\ \sf{ \angle P=65{}^{\circ}\:\:\:\: \angle R=85{}^{\circ}}\end{cases}$

• We have to find the angle Q

• We know that the

$\boxed{\sf{Sum\:of\:angles\:of \triangle=180{}^{\circ}}}$

Now :-

$\bf\underline{\red{According\:to\: Question}}$

$\sf\implies 180{}^{\circ}=\angle P+\angle Q+\angle R\\ \\ \sf\implies 180{}^{\circ}=65{}{\circ}+85{}^{\circ}+\angle Q\\ \\ \sf\implies 180{}^{\circ}=150{}^{\circ}+\angle Q\\ \\ \sf\implies 180{}^{\circ}-150{}^{\circ}=\angle Q\\ \\ \sf\implies 30{}^{\circ}=\angle Q$

• The third angle of triangle which is angle Q is 45°

$\boxed{\sf{\purple{\angle R=30{}^{\circ}}}}$
