The angles all form vertical angles. The ones labeled are vertical to each other and the ones not labeled are vertical to each other. Vertical angles are congruent, therefore, 2x + 50 = 7x. Solving for x you get 50 = 5x and x = 10. That means that that set of vertical angles each have a measure of 70. That's 140 so far. Around the "circle" created by those angles is a total degree measure of 360. So 360 - 140 = 220. Divide that in half to get the measure of angle BED and its vertical angle AEC. So your angle measure, BED is 110.
A
It is a first degree polynomial (aka linear because its highest power is 1) and it has two terms (2x and 8)
It does not have eight terms and is not a monomial (one term ie 3x^2)
Answer:
The monthly cost = $9 + $0.39x
Step-by-step explanation:
The hole is x+4=0 because (x+4) is canceling out so the hole x=-4
