Solve for x I need help on this question
AlexFokin [52]

Answer:

x\approx7.8

Step-by-step explanation:

In relation to the given angle, we are given the triangle's opposite side and hypotenuse. Therefore, we use the sine function to set up a proportion and solve for the opposite side:

sin(\theta)=\frac{opposite}{hypotenuse}

sin(23^\circ)=\frac{x}{20}

20sin(23^\circ)=x

x=20sin(23^\circ)

x\approx7.8

Therefore, the length of the opposite side is about 7.8 units

Find the slope of the line that passes through (10, 3) and (7, 11).
Vadim26 [7]

Answer:

Slope of the line is -\frac{8}{3}.

Step-by-step explanation:

Given points are:

(10, 3) and (7, 11)

Here,

x1 = 10 and y1 = 3

x2 = 7 and y2 = 11

Slope of a line is given by

m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{11-3}{7-10}\\\\m = \frac{8}{-3}

Therefore,

Slope of the line is -\frac{8}{3}.

E bisects line segment df. df=2y, and ef=8y-3. find de, ef, and df.
Usimov [2.4K]

1/2DF = EF

1/2(2y) = 8y - 3

  • Multiply 1/2 * 2y.

y = 8y - 3

  • Subtract 8y from both sides.

-7y = -3

  • Divide both sides by -7.

y = 3/7

  • Plug 3/7 for y into DF and EF.

DF: 2(3/7) = 6/7

EF: 8(3/7) - 3 = 24/7 - 3 = 3/7

EF = DE because they are bisected, so DE = 3/7
