Question

the measure of the angles of a triangle are represented by (2x)°, (x+40)°, and (x)°. what is the measure of the largest angle of the triangle?

Answer 1

Sum of angles of a triangle : 180°

So, 2x + x + 40 + x = 180

4x + 40 = 180
4x = 180 - 40
4x = 140
x = 35°

So, angles -
x = 35°
2x = 2×35° = 70°
x + 40 = 35°+40° = 75°

So, largest angle - 75°
