54 is 75% of x.
75% of x:
75% of x is (3/4)x and 75% of x is 54. Set (3/4)x equal to 54:
54 is 75% of
72.
Answer:
b. (√15)/4
Step-by-step explanation:
Since Sin Ф = (opposite side)/Hypotenuse, we have 2 sides of a right triangle.
Use Pythagorean theorem to solve for the missing leg (the adjacent side)
1² + b² = 4²
1 + b² = 16
b² = 15
b = √15
So the adjacent side is √15, so Cos Ф = (√15)/4
Tina has two bags of counters. Bag A has 5 red and 3 blue. Bag B has 4 red and 5 blue. The probability that tina takes two blue counters in fraction is 15/72
<h3>What is the probability?</h3>
Given parameters:
Bag A= 5 red + 3 blue
Bag B = 4 red + 5 blue
Hence,
Total counters in bag A = 5 +3 = 8
Total counters in bag B = 4 + 5 = 9
Now let determine the probability that she takes two blue counters
Probability = 3 /8 × 5 /9
Probability = 15 / 72
Therefore 15 / 72 is the probability that two blue was taken.

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!
