Question

The angle measures of a triangle are marked below. Find the value of X.
(8x) degree 64 degree (9x-3)

Answer 1

To find the value of X, we need to use the fact that the sum of the angles in a triangle is always 180 degrees.

So, we can set up an equation:

8x + 64 + (9x-3) = 180

Combining like terms:

17x + 61 = 180

Subtract 61 from both sides:

17x = 119

Divide by 17:

x = 7

So, the value of X is 7.
