Am I suppose to be looking at a picture?
Answer: 21
Step-by-step explanation:
we have two simple equations:
1) 70=100%
2) x=30%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
70/x=100%/30%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 30% of 70
70/x=100/30
(70/x)*x=(100/30)*x - we multiply both sides of the equation by
70=3.33333333333*x - we divide both sides of the equation by (3.33333333333) to get x
70/3.33333333333=x
The fore, the answer is 21

Answer:
The tower is about 235 m.
Step-by-step explanation:
Let x be the height of the tower
tan θ = opp / adj
tan 78 °= x / 50
x = 50 tan 78 °
x = 235
∴ The tower is about 235 m.
Hope this answer helps you :)
