Answer:263.9 in squared
Step-by-step explanation:
Find the area of the whole circle
Multiply area times the angle of the shaded region by total angle
Get answer
(pi)(12^2) = Area of whole
(Whole area)x(210deg/360deg)
=== 263.9 in squared
Answer:
41.7feet
Step-by-step explanation:
From the question we are given the following
angle of depression = 50°
Distance of the pole from the base of the feet = 35feet (Adjacent)
Required
height of the school (opposite)
Using the SOH CAH TOA identity
Tan theta = opp/adj
Tan 50 = H/35
H = 35tan 50
H = 35(1.1918)
H = 41.7feet
Hence the height of the school is 41.7feet
Answer:

Step-by-step explanation:

Writing each term in its factors:

We find out that 5 is the GCF of all the terms
Factoring out 5 from the given expression.

Factors: 5 and 
Thus:

<span>(2n + 2)(2n – 2)
= (2n)^2 -2^2
= 4n^2 - 4
