Answer:
There are 50 boys
Step-by-step explanation:
girls to boys - 2:4
so 25x2=50
The answer:

Explanation to your question:
Since the sin of theta is 0.3, we can reasonably deduct that the opposite side to theta has a ration of 3 to 10 to that of the hypotenuse. Thus, the adjacent side to theta, using the pythagorean theorem, will be root91. Therefore, since the cosine of theta is the adjacent/hypotenuse, we get root 91/10
250
1250 & 250 divided by 1250
33-4(3)
33-12
21
The answer is 21
