Take the first 9 is in yours tens place so you want to take the second 9 and round up because anything 5 or more goes up and 4 or less stays the same
We are given

we know that

so, we get
opposite =7
adjacent=24
now, we can find hypotenuse


now, we can draw triangle and then switch vertices accordingly
we can find cos(B) using second triangle

In second triangle:
adjacent=7
hypotenuse =25
so, we get
................Answer
Answer:
The answer is C.
Step-by-step explanation:
3/4 is equal to 0.75. If you combine 0.75 with -20, then it is 20.75.
Your answer should be 314
4 x 16=64
10 x 25 (25 is the height)=250
64 + 250=314
