This is the concept of trigonometry, we are required to calculate the number of floors the building has given the information above;
# floors=[height of the building]/[height of each floor]
height of each floor=17 ft
let the height of the building be,h.
h is given by;
tan theta=opposite/adjacent
theta=80
opposite=h
adjacent=75 ft
thus
tan 80=h/75
h=75 tan 80
h=425.35 ft
thus the number of floors will be:
425.35/17
=25.020≈25 floors
Why do math got to be so complicated
Answer:
There are 60 lemon cookies.
Step-by-step explanation:
1/2/240=120
3/20/240=36
1/10/240=24
120+36+24=180
240-180=60
Answer:
25
Step-by-step explanation:
a1 = - 3 Given
d = 2 Given
n = 15 Given
Formula
tn = a1 + (n - 1) * d
Substitute and solve
t15 = -3 + (15 - 1) * 2 Calculate what's in the brackets.
t15 = -3 + 14*2 Combne
t15 = -3 + 28 Add the two terms
t15 = 25
