Question

Find the value of x.

Answer 1

what's the sum of the internal angles in a triangle?

Answer 2

@jdoe0001 180?

Answer 3

so.... notice the 90 degrees down below... .so if that angle down there is 90 degrees
that means that the other 2 have to sum up to 90 degrees too, because 90 + 90 = 180 total

so the other 2 angles, that is 2x and x+15 will add up to 180, so \(\bf 2x+(x+15) = 180\) solve for "x" to find what "x" is

Answer 4

@jdoe0001 so does x = 55?
