(B) 70°
(C) 100°
(D) 50°​

Answer 1

$\rm\underline\bold{Answer \purple{\huge{\checkmark}}}$

(C) 100°

Answer 2

Answer:

Option A is the correct answer ✔️ 90°

Sum of the 3 angle = 180°

We know, angle 1 = 30° and angle 2= 60°

Let us take angle 3 as "X".

30+60+X = 180

90+X = 180

X = 180-90

X = 90°

Hence, the 3 angle is 90°.
