Question

The angle measures of a triangle are shown in the diagram.

What is the value of x?

for the triangle one of the corner is (5x) the other is (74) and the last one is (4x+7)

Answer 1

To find the value of x, we know that the sum of the angles in a triangle is 180 degrees.

So, we can write the equation:

5x + 74 + 4x + 7 = 180

Combine like terms:

9x + 81 = 180

Subtract 81 from both sides:

9x = 99

Divide by 9:

x = 11

Therefore, the value of x is 11.
