Since the sum of all three angles in a triangle is always 180°, you know the measure of angle A, and you know that the measures of B and C are equal, you can set up an equation like this:

180 = 2x + 70

Subtract 70 from both sides:

110 = 2x

Isolate x:

55 = x

So, the measure of angle B (and C) is 55°. 

Hope this helped!! xx

The measure of angle B should be 55.

  • The calculation is as follows:

180 = 2x + 70

180 - 70 = 2x

2x = 110

x = 55 degrees

So, angle B and angle c should be of 55 each.
