Answer:
20.78feet
Step-by-step explanation:
The question made us to understand that the man is standing and also there is angle of elevation, then we need to draw a right triangle having a base equal to 36 feet with an angle from the base to the top of the pole which is 30 degrees.
tan= opposite side / adjacent side
Let height of the pole =h
Tan(30)= h/36
But tan 30degree= 1/√3
h= 36 × 1/√3
h= 20.78feet
Therefore, the height of the pole= 20.78feet

Answer:
17million
Step-by-step explanation:
5+(2m)+m+2+m=54
9+3m=54
3m=45
m=15
Farid=15+2=17
Answer:
10
Step-by-step explanation:
"When 9 is increased by 3x"
THis means 9 + 3x
"The result is greater than 36"
We use greater than sign and 36
So we can write:
9 + 3x > 36
SOlving this via equation rules and algebra:
9 + 3x > 36
3x > 36 - 9
3x > 27
x > 27/3
x > 9
This means x is everything greater than 9, which satisfies the equation. So in terms of integers, it can be 10, 11, 12, 13...anything above
We want to find the least possible integer value of x, so it is definitely 10
