To answer your question, it is shown in the image below:
Given:
bottom of the plank or ground is 9 feet from the wall
length of the plant is 41 ft
height of the wall is unknown.
Let us use the Pythagorean theorem.
a² + b² = c²
a² + (9ft)² = (41ft)²
a² + 81 ft² = 1,681 ft²
a² = 1,681 ft² - 81 ft²
a² = 1,600 ft²
√a² = √1,600 ft²
a = 40 ft
The height of the wall is 40 ft.
Tan(58)=10/x
x=10/tan(58)
x= 6.2
Answer:
just mark points it is very easy
First, you have to answer the question in simplest form:
<span>3x - 4y = 5 (Subtraction property of equality) Subtract both sides by -3x.
-4y = -3 +5 (Divide both side by -4.))
</span>y = 3/4x(slope) 4/5 y-intercept.
