Answer:
The length of the ladder is 14.5 ft
Step-by-step explanation:
For a right triangle
sinx = opposite / hypotenuse
Since we know the angle and the opposite side, we can calculate the hypotenuse
sin 64 = 13/ hypotenuse
Multiply each side by the hypotenuse
hypotenuse * sin 64 = 13
Divide by sin 64
hypotenuse = 13/sin 64
hypotenuse=14.4638
Rounding to the nearest tenth
14.5
<em>C) 52 m²</em>
- Step-by-step explanation:
<em>A = 2(lw + lh + wh)</em>
<em>l = 4m</em>
<em>w = 3m</em>
<em>h = 2m</em>
<em>A = 2(4m×3m + 4m×2m + 3m×2m)</em>
<em>= 2(12m² + 8m² + 6m²)</em>
<em>= 2×26m²</em>
<em>= 52m²</em>
