Step-by-step explanation: (I'm not gonna' do it <em>all</em> for you tho)
to convert from <u>percent to fraction</u>:
70% = 
to convert from <u>fraction to percent</u>:
= 55%
to convert from <u>fraction to decimal</u>:

to convert from <u>decimal to fraction</u>:

to convert from <u>percent to decimal</u>:
0.2% = 
to convert from <u>decimal to percent</u>:
% = 40%
With that, you can solve the rest on your own
Answer:
x = 20
Step-by-step explanation:
x + 29 = 49
- 29 - 29
x=20
You are solving for the height. Use the formula:
c² - b² = a² in which c = hypotenuse
(13)² - (5)² = a²
Simplify
169 - 25 = a²
144 = a²
Isolate the a. Root both sides
√144 = √a²
a = √144
a = √(12 x 12)
a = 12
C) 12 feet is your answer
~
Using the formula;

You should get
12.1655 or
12.2 units.
Hope this helps you with Coordinate Solving!
