we know that
in the right triangle ABC
the value of cosine of angle x is equal to

we have

substitute the values

Find the measure of angle x

Round to the nearest whole degree

therefore
<u>the answer is</u>

So.
.
Let's get started with formulas.
.
I KNOW you hate formulas!! So do I, but we have to use them. No "buts".
.
So, how many minutes are in 2 weeks?
.
Search it up. For your convenience, it is 20,160 minutes.
.
Well, I think you have your answer, since each quiz is 5 minutes, 5 times 50 (5 x 50) is 2,500 minutes.
.
Yes, you can do 50 quizzes and MUCH MUCH more in 2 weeks.
.
Hope I helped!!
Answer:
385 golf balls
Step-by-step explanation:
margin of error = (z*)(s) / sqrt n
where z* = 1.96 with 5%/ 2 = 0.025 area in each tail
margin of error = (z*)(s) / sqrt n
1.2 yards = (1.96)(12 yards) / sqrt n
solve for n
n = 384.16
385 golf balls (always round up)
