How do i find the area of a trapezoid (pictures provided)

Mathematics
1 answer:
scoray [572]3 years ago
5 0

Answer:

(10x - 5) square units.

Step-by-step explanation:

Let the lengths of equal sides be x units.

Hence, AB + AD + DC = x + x + x = 3x

Therefore, BC = 3x - 2

Area  \: of \:  trapezoid  \\ =  \frac{1}{2} (AD + BC)  \times 5 \\  = \frac{1}{2} (x + 3x - 2)  \times 5  \\ = \frac{1}{2} (4x - 2)  \times 5  \\ = \frac{1}{2} \times 2 (2x - 1)  \times 5  \\  = (2x - 1) \times 5 \\  = (10x - 5) \:  {units}^{2}

Find the value of y.
Natali [406]

Answer:

y=7

Step-by-step explanation:

The two given angels are congruent so they must be equal in measure.

Set them up equal and find y.

8y = 5y + 21, subtract 5y from both sides

8y -5y = 21, combine like terms

3y = 21, divide both sides by 3

y = 7

A ladder is leaning against a building and makes a 28 degree angle with the ground. the top of the ladder reaches up the buildin
Digiron [165]

The length of the ladder is 75ft.

<h3>What is hypotenuse?</h3>

The longest side, or hypotenuse, of a right-angled triangle is the side that faces away from the right angle. The Pythagorean theorem asserts that the hypotenuse's square length equals the sum of the squares of the lengths of the other two sides, and this can be used to determine the hypotenuse's length.

<h3>According to the information:</h3>

The ladder makes an angle of 28° with the ground and the top of the ladder reaches 35ft

Therefore, we have:

Sineα = opposite/hypotenuse

Where:

Opposite = 35

Hypotenuse = Length

α = 28°

substitute values and solve for the length, as following:

Sine(28) = 35/Length

Length = 35/Sine(28)

Length = 75ft

Therefore,

The length of the ladder is 75 ft.
