Answer:

The answer is A.

Step-by-step explanation:

The angle your looking at is a 90 degree angle therefore if you split it in half that makes each side 45 degrees. Just off of the fact that B says, "The measure of the smaller angle is 55 degrees" already makes it completely wrong since it would be have to be smaller than 45 degrees.

Factor 8x^3y + 38x^2y - 10xy

Sophie [7]

Answer:

2xy(x+5)(4x−1)

Step-by-step explanation:

1 Find the Greatest Common Factor (GCF).

GCF = 2xy

2 Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

2xy (8x^3y + 38x^2y/2xy + −10xy/2xy)

3 Simplify each term in parentheses.

2xy(4x^2 +19x−5)

4 Split the second term in 4x^2+19x-5 into two terms.

2xy(4x^2 +20x−x−5)

5 Factor out common terms in the first two terms, then in the last two terms.

2xy(4x(x+5)−(x+5))

6 Factor out the common term x+5.

2xy(x+5)(4x−1)

Tems11 [23]

Answer:

D. 5(x^2+5)

Step-by-step explanation:

5x^2+25

Viewing the two terms 5 is divisible by both

5X^2/5 +25/5

X^2+5

Therefore the equation will be represented by

5(x^2+5)

Two vertical buildings 57 meters apart are 158 meters and 237 meters high. Find the angle of elevation from the top of the short

miskamm [114]

Given :

Two vertical buildings 57 meters apart are 158 meters and 237 meters high.

To Find :

The angle of elevation from the top of the shorter building to the top of the taller building.

Solution :

Distance between height of building, h = 237 - 158 = 79 m.

Distance between these building , d = 57 m.

Now,

$tan\ \theta = \dfrac{h}{d}\\\\tan\ \theta = \dfrac{79}{57}\\\\tan\ \theta = 1.386\\\\\theta = tan ^{-1} 1.386\\\\\theta = 54.19^{\circ}$

Therefore, the angle of elevation from the top of the shorter building to the top of the taller building is 54.19°.

Hence, this is the required solution.
