Question

What is the value of x?

Answer 1

x = 37

Explanation:

So we know that all 3 angles will equal 360 degrees.

Therefore, we can subtract 99 from 360:

360 - 99 = 261

To find the other two, combine like terms:

4x + x = 5x

So we now know:

5x + 76 = 261

Subtract:

261 - 76 = 185

Then divide:

185 / 5 = 37

So x = 37!
