Answer:

x = 25

Step-by-step explanation:

Equiangular triangle is also equilateral triangle.

This means their sides are of equal length.

So, AB = BC = AC

Consider AB = BC

3x - 5 = 2x + 20

3x - 2x = 20 + 5

x = 25

Check:

Length of AB = 3x - 5 = 3(25) - 5 = 75 - 5 = 70

Length of BC = 2x + 20 = 2(25) + 20 = 50 + 20 = 70

Length of AC = 4x - 30 = 4(25) - 30 = 100 - 30 = 70
