If segment FD = 20 units and segment DE = 52 units, what is the value of b? Round the solution to the nearest hundredth.
Readme [11.4K]

Answer:

b = 22.62^{o}

Step-by-step explanation:

Since the triangle is a right angled triangle, the appropriate trigonometric function can be applied to determine the value of b.

Thus, to determine the value of b;

Sin θ = \frac{opposite}{hypotenuse}

Sin b =  \frac{20}{52}

         =  \frac{20}{52}

          = 0.38462

⇒ b = Sin^{-1} 0.38462

  = 22.6202

b = 22.62^{o}

The measure of angle E (= b) is 22.62^{o}.

Radda [10]

Answer: The base is 18.3ft

Sam wants to build a wooden deck on his patio, which is in the shape of a parallelogram. The area of the patio is 280 ft2. Find the base. Round your answer to the nearest foot. (height=5x)(base=6x)

Step-by-step explanation:

Given;

Area = 280ft^2

height = 5x

Base = 6x

The area of the parallelogram A can be written as;

Area = base × height

A = b×h

Substituting the values of Area, base and height.

280 = 5x × 6x

280 = 30x^2

x^2 = 280/30

x = √(280/30)

Since the base = 6x ;

Substituting the value of x.

Base = 6x = 6(√(280/30))

Base = 18.3ft

The base is 18.3ft
