Answer:
10
Step-by-step explanation:
pi is 3.14...
pi - 1 is 2.14...
question becomes 1<2.14x and 2.14x < 10
1/2.14 < x, 0.46... < x
x < 10/2.14, x < 4.67...
combining
0.46< x < 4.67
x can be 1, 2, 3, 4
D because ugh I don’t feel like explaining
The answer is 21 - 17, which = 4.
Or you could +4 to CM (17) which equals CQ (21)
The correct answer is 18.7.
So I kind of went an indirect way but I can explain it all. I ignored the 15°. The box in the right correct means that angle is 90°. Since a triangle is always 180°, I subtracted 90 and 15 from 180. That gives you 75°. Now that you know that you can use tangent from SOH CAH TOA. So... tan75= x/5 which turns into 5tan75°. Plug that into a calculator and you get 18.66 which rounds to 18.7.
If you need anymore help I'm here. Hope I helped :) Good luck!
