Question

Find the value of x.

It’s a right angle. One of the angles says (3x) degree other side says (4x-1) degree

Answer 1

x=13

Explanation:

The sum of the angles of a triangle add to 180 degrees

3x+ 4x-1 +90 =180

Combine like terms

7x +89 = 180

Subtract 89 from each side

7x +89-89=180-89

7x =91

Divide each side by 7

7x/7 =91/7

x = 13
