Question

Given the indicated parts of triangle ABC with y=90°, approximate the remaining parts. a=31, b=9

Answer 1

To approximate the remaining parts of triangle ABC with y=90°, we need to find the measures of the angles. We are given that angle A is 31 and angle B is 9.

To find angle C, we can use the fact that the sum of angles in a triangle is 180°. So, angle C is 180 - 31 - 9 = 140°.
