Answer:
Step-by-step explanation:
This triangle is a polygon. By definition, all the exterior angles of ANY polygon add up to equal 360 degrees. So we add up all the exterior angles and solve for x. That's the first step.
7x - 2 + 9x - 31 + 4x + 33 = 360
Combining like terms gives us
20x + 0 = 360 or simply
20x = 360 so
x = 18
In order to find the value of the angle exterior to angle C, we sub 18 in for x:
7(18) - 2 = 124

3x-4=-19
you add -4 to both sides and get 3x=15 then divide 3 by both sides and get x=5 (15 divided by 3 is 5)
Answer:
the answer is 18.1 1/10 is the same thing as .1
