Answer:
9
Step-by-step explanation:
This means that 9/(9+72)=(3x-20)/(3x+36), or 1/9=(3x-20)/(3x+36). Cross-multiply to get that 27x-180=3x+36, so 24x=216, and x=9.
Answer:
90 degrees because A is an acute angle so x equals 45 degrees and so I multiply that by 2
Step-by-step explanation:
Answer:
0
Step-by-step explanation:
slope = y2 - y1 / x2 - x1
(-2,5) (6,5)
5-5/-2-6
0 / -8
slope is 0
