Question

In ∆ABC , angle A=(3x-5)°, angle B(2x+15)° and angle C=(4x+35)°. Find the measures of each angle of the trian​

Answer 1

In triangle ABC

Angle A + B + C = 180 degrees (by Angle sum property)

3x-5 + 2x+15 + 4x+35 = 180 degrees

9x + 45 = 180 degrees

9x = 180 - 45

9x = 135

x = 135/ 9

x = 15

Angle A = try putting the values and find the solutions for each

Angle B =

Angle C =
