Answer:
The angle of elevation of the sun is .
Step-by-step explanation:
Let be the angle of elevation of the sun as shown in the diagram.
Then the side length which is feet is opposite to
and the side length which is
feet is adjacent to
.
Therefore we use the trigonometric ratio that involves the opposite and adjacent sides, which is the tangent ratio.
We solve for to get,
To the nearest degree, the angle of elevation is
Answer:
Step-by-step explanation:
Given that,
The radius of a cone, r = 6 inches
The slant height of the cone, l = 10 inches
We need to find the total surface area of the cone. It is given by :
Substituting all the values,
So, the total surface area of the cone is .
Answer:
From the given statement the value of b is calculate as 8
Step-by-step explanation:
The given statement is
+ 1 = 3
This is a form of simple equation
= 3 - 1
= 2
Or, b = 2 × 4
I.e b = 8
Hence from the given statement the value of b is calculate as 8 Answer
