Let Angle A = X
Since Angle B is the same, angle B is also X
Then angle C = X +45
Add the 3 angles together: X +X +X +45 = 3x+45
That equals 180 degrees:
3x+45 = 180
Subtract 45 from both sides:
3x = 135
Divide both sides by 3:
X = 135/3
X = 45
Angle A = 45
Angle B = 45
Angle C = 45+45 = 90
Cos = adjacent over hypotenuse
cos33 = b/170
170cos33 = b
b = 142.574 inches
An expression is a mat scentence but not a complet on.Example:2x3. Or a x 5. I hope I said it clearly for you.
