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
75 is the answer to this equation
Answer:
30
Step-by-step explanation:
boys: girls : total
3 7 3+7 =10
The total number of students must be a multiple of 10
The class size is between 22 and 34
The only multiple of 10 between those numbers is 30
10,20,<u>30</u>,40
Therefor the class size must be 30
Answer:
t = 12
Step-by-step explanation:
t-5=7
You need to undo subtraction, so you add 5. Undo-ing means that you are making the ened product 0 which cancels it. What you do to one side of the equal sign, you do to the other. -5 plus 5 is 0 which cancels out. The reason it is -5 is the sign in front of the 5, indicates that it is a negative 5. You then add 5 to 7. You are then left with
t=12
Answer:
x= 36
