Question

The three inside angles (A, B and C) of a right angled triangle are in the ratio 7:18:11

The smallest angle is 35°

Work out out angles a,b and ,

Answer 1

Angle A =35 degrees, Angle B = 90 degrees, and Angle C = 55 degrees

Explanation:

So all the angles added up would be 180. Let's use the variable x. The angles would be 7x, 18x, and 11x.

The smallest angle is 35, and 7x is the smallest out of all them since x has to be positive.

7x = 35

x = 5

Then substitute x into each angle.

They would be 35 degrees, 90 degrees, and 55 degrees
