I’m not sure what a natural number means, but some simple ones are
2 x 47
10 x 9.4
12 x 7
-4-2 divided by 5 +3
-6/8
The slope would be -3/4
maximum area is a square
the side of the square would be 52/4 = 13 feet
area = 13*13 = 169 square feet

- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] sinθ = opposite over hypotenuse
Step-by-step explanation:
<u>Step 1: Identify</u>
Angle θ = 35°
Opposite Leg = <em>x</em>
Hypotenuse = 15
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [Sine]: sin35° = x/15
- Isolate <em>x</em>: 15sin35° = x
- Rewrite: x = 15sin35°
- Evaluate: x = 8.60365
- Round: x ≈ 8.6
Answer:
60°
Step-by-step explanation:
Let angle BAE = angle ACD = x
BCD = AEC = 60°
EAC + FCA + ECF + AEC = EAC + x + 60° + 60° = 180°
EAC = 60° - x
BAC = EAC + BAE = 60° - x + x = 60°
