<h2>Answer:</h2>
8.75 feet
<h2>
Step by step:</h2>
Given that a 12 foot ladder leans against a building seven feet above the ground.
By using trigonometry ratio, the angle between the ladder and the ground will be
SinØ = opposite/ hypothenus
SinØ = 7 / 12
SinØ = 0.58333
Ø = Sin^-1(0.58333)
Ø = 35.69 degree
At what height would an 15 foot ladder touch the building if both ladders form the same angle with the ground?
Using the same trigonometric ratios
SinØ = opposite/hypothenus
Sin 35.69 = opposite/ 15
Cross multiply
Opposite = 15 × sin 35.69
Opposite = 8.75 feet
Therefore, the ladder will touch the building if both ladders form the same angle with the ground at height 8.75 feet.
3(y+10) = 3(3). For additional simplification, the answer may be written as
y+10 = 3
The volume of the given composite figure is: 375 m³.
<h3>What is the
Volume of a Composite Figure?</h3>
Volume of the composite figure = volume of triangular prism at the bottom + volume of rectangular prism at the top.
Volume of the composite figure = 0.5 * b * h * length + (l)(h)(w)
= 0.5 * 5 * 4 * 5 + (13)(5)(5)
= 50 + 325
Volume of the composite figure = 375 m³
