Answer:
In words, Cosine theta equals plus or minus square root of seven over 4,tangent theta equals plus or minus three over root seven
Step-by-step explanation:
Given that sin ∅ =3/4 It means the ratio of the opposite side to the hypotenuse side is 3:4.
Using the Pythagoras theorem we can calculate the hypotenuse adjacent as follows.
a²+b²=c²
a²=c²-b²
a²=4²-3²
a²=16-9
a²=7
a=√7
Then Cos ∅= opposite/ adjacent
=√7/4
Then Tan ∅ = opposite/adjacent
=3/√7
In words, Cosine theta equals plus or minus square root of seven over 4,tangent theta equals plus or minus three over root seven.
I think its 1.25ft but i could be wrong... sorry if im wrong
Assuming the h is not in the exponent, R would equal The square root of V over 3.14h
Net A is the correct net.
The surface area of the prism is 72 in squared
SA= 1/2bhH
SA= (0.5)(4)(5)(7.2)
SA= 72 in. squared
C
4/8 equals 1/2 the rest are 1/2 but 12/36 is 1/3
