NEED HELP NOW A histogram is being made for the following set of data. If the length of each interval is going to be 7, what will be the frequency of the first interval?

78, 92, 98, 87, 86, 72, 92, 81, 86, 92

A. 3
B. 1
C. 2
D. 4

If you could also explain how you got you're answer that would also be nice.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

answer:   c ?
