Answer 2

Answer:

Question:-

Find the angles of a triangle which are in the ratio 3: 4:5

Property Used:-

• Sum of angles of the triangle is 180°.

Answer:-

Given:

▪︎1st angle = 3x

▪︎2nd angle = 4x

▪︎3rd angle = 5x

To Find:

Measure of all angles.

Solution:

According to property of a triangle;

Sum of angle of triangle = 180°

= 3x+4x+5x = 180°

= 12x = 180

= x = 180÷12

Hence, x = 15°

▪︎1st angle = 3x = 3×15 = 45°

▪︎2nd angle = 4x = 4×15 = 60°

▪︎3rd angle = 5x = 5×15 = 75°
