Answer 1

Answer:

Here is the answer.

Explanation:

Answer 2

Explanation:

From ques. triangle ABC is a right angled triangle.

AC² = BC² + AB²

AC² = ( 5 ) ² + ( 12 ) ²

AC² = 25 + 144

AC² = 169

AC = √ 169

AC = 13 ( As power ² came this side and became root over )

According to angle sum property of a triangle :-

Angle ( A + B + C ) = 180°

A + 90 ° + B = 180°

A + B = 180° - 90 °

A + B = 90 °

2A = 90°

A = √ 90°

A = 45°

*Hence proved.
