Question

the angles of triangle are in the ratio 3 : 7 : 8 ratio find the angle of triangle

Answer 1

required answer is this

Answer 2

The angles of the triangle are 30°,70°, and 80°

Explanation:

Given:

1. The angles of a triangle are in the ratio 3:7:8

To find:

The angle of a triangle

Formula:

∠A+∠B+∠C= 180°

Solution:

==> Sum of the angle = 180°

==> The ratio of angle = 3:7:8

==> ∠A = 3x

==> ∠B = 7x

==> ∠C = 8x

==> Apply the values in the formula

==> 3x+7x+8x = 180°

==> 18x = 180°

==> x = 180÷18

==> x=10

==> ∠A = 3x

==> ∠A = 30°

==> ∠B = 7x

==> ∠B = 70°

==> ∠C = 8x

==> ∠C = 80°

The angles of the triangle are 30°,70°, and 80°.
