hmmm without the value of X i can't exactly find the value of y...give me the value of x and i can solve for you
The triangle is iscosceles where angle A = angle B
So
34 = x - 5 add 5 to both sides
39° = x .....so angle B also equals 34°
So
34 + 34 + 4y = 180
68 + 4y = 180 subtract 68 from both sides
4y = 112 divide both sides by 4
y = 112 / 4 = 28
Edit to correct an idiotic error....LOL!!!!!
