Question

Answer these two questions I need help ​

Answer 1

This is the answer of the first question...

second question:-

Theorem 1: Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.

Proof:

Consider a ∆ABC, as shown in the figure below. To prove the above property of triangles, draw a line PQ←→ parallel to the side BC of the given triangle.

Since PQ is a straight line, it can be concluded that:

∠PAB + ∠BAC + ∠QAC = 180° ………(1)

I am sure that the answers are correct but....there is a problem in the second question that I can't draw the figure due to some network issues.....I tried a lot but...it's not working.....I hope the remainings could help you..
