Answer:
C = 64.145º
Step-by-step explanation:
The Law of Sines is as follows:
=
= 
The problem can be draw as the picture attached.
Now, the values of the sides and angles can be substituted into the Law of Sines, and because all parts are equal, only two are needed:
= 
Next, cross-multiply:
7sin40º = 5sinC
Then, divide both sides by 5:
= sinC
Finally, take the inverse sin of the left side and convert into a decimal:
C =
(
)
C = 64.145
Answer:
704π m^2
Step-by-step explanation:
Given data
radius r= 16m
Slant height l= 28m
Required
The surface area of the cone
The expression for the surface area is given as
T.S.A=πrl+πr^2
substitute
T.S.A=π*16*28+π*16^2
T.S.A=448π+256π
T.S.A=704π m^2
Hence the T.S.A is 704π m^2
Answer: A.)
Step-by-step explanation:
We can plug in the values of this point to find b
-4 = 17 (3) +b
We will multiply 17 times 3
-4 = 51 + b
We then subtract by 51 on both sides
-55 = b
So the full equation will be
y = 17x - 55
