Answer:
1st ∡ = 15.5°
2nd ∡ = 77.25°
3rd ∡ = 87.25°
Step-by-step explanation:
1st ∡: x
2nd ∡: y
3rd ∡: z
Equations we can create from data given in problem:
y + z = 5x
z = 5x + 10
We have enough expressions to create an equation:
x + 5x + 5x + 10 = 180
11x = 170
x = 15.5
y = 5(15.5) = 77.25
z = y + 10 = 87.25

Simple Interest Rate Formula: 
- <em>P</em> is principle amount
- <em>r</em> is rate
- <em>t</em> is time (in years)
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>P</em> = 7300
<em>r</em> = 3% = 0.03
<em>t</em> = 10
<u>Step 2: Solve for </u><em><u>A</u></em>
- Substitute in variables [Simple Interest Rate Formula]:

- (Parenthesis) Add:

- Evaluate exponents:

- Multiply:

198 x 0.05 = 9.9
198 - 9.9 = 188.1
188.1 x 0.07 = 13.167
188.1 + 13.167 = 201.267
He weighs 201.3 pounds if you round it.
