Answer:
49 degrees
Explanation:
recall that in a triangle, the angles add up to 180.
so let's set up the equation
x+2x+(x-16)=180 degrees
4x-16=180
4x=196
and so
x=49 degrees
hope this helped
make sure to convert x into angles for each of the angles if it asks for the angles (plug the values in, so 2x-10 would be 2(49)-10, which is 88 i think
