Question

Solve for the variable. Then, find the measure of the angles. You will need to set up an equation to solve, remember the sum of the angles of a triangle is 180.

Answer 1

T = 90, x = 13, A = 51, B = 39

Explanation:

The figure is very hard to read, but assuming A=4x-1 and B = 3x, here's the solution:

T = 90 (it is shown as a right angle)

(4x -1) + 3x + 90 = 180 (sum of the interior angles of a triangle = 180)

Now solve for x:

7x + 89 = 180

7x = 91

x = 91/7 = 13

A = 4(13) - 1 = 51

B = 3(13) = 39
