Question

fi​nd the missing angles in a ∆
(it is ABC)​

Answer 1

Answer:

A = 15     B = 90     C = 75

Step-by-step explanation:

The angle B is 90 degree. You can understand it by the sign of 90 degree made between the 2 line segments. This is a right angled triangle.

For Angle A---->

The angle sum property says that sum of all angles in a triangle is 180.

So A+B+C = 180

A + 90 + 75 = 180

A = 180 - 90 - 75

A = 15 degree

Hope it helps :)

Answer 2

Answer:

Angle ABC is right angle so,

First angle is 75°

Second angle is 90°

And the third angle is 180- 165= 15°
