Step-by-step explanation:
<A=90°(opposite Angles)
➜2x+x+90=180
➜3x+90=180
➜3x=180-90

Answer:
Can you elaborate, please?
Step-by-step explanation:
The y-difference between the points is 5-(-6) = 11. One-fifth of that is 11/5 = 2.2. Adding that to the y-value of point X means ...
... the y-value of point Y is -6+2.2 = -3.8
Any of the 11 man can be chosen, and combined with any of the 8 women.
Assume we select man1. The selected committee can be:
(m1,w1), (m1,w2), (m1,w3), (m1,w4), (m1,w5), (m1,w6), (m1,w7), (m1,w8),
so there are 8 committees selections with man1 in them.
we could repeat the same procedure for the remaining 10 men, and get 8 committees where each of them is a member.
so there are 11*8=88 ways of choosing 1 man and 1 woman.
Answer: 88
