Answer:

A. 90°+m∠4

Step-by-step explanation:

Also

∠ A + ∠ C = 180 o = ∠ B + ∠ D

⇒ 2 x+ ( 3 x − 5 ) = 180 0 = ( x + 5 ) + ∠ C

5 x − 5 = 180

Add 5 to both sides

5 x = 185

Divide both sides by 5

x = 185 5 = 37

But it was A. 90°+m∠4

Which is the slope of the line that passes through the points (3,5) and (8,7)?

Hatshy [7]

Hi there!

»»————-　★　————-««

I believe your answer is:

$m=\boxed{\frac{2}{5}}$

»»————-　★　————-««

Here’s why:

The formula for the slope of two given lines given is 'rise over run'.

⸻⸻⸻⸻

$\boxed{\text{Slope Formula:}}\\\\\frac{y_2-y_1}{x_2-x_1}\\\\\rightarrow (x_1,y_1),(x_2,x_1) - \text{Two Points Given}$

⸻⸻⸻⸻

We are given the points (3,5) and (8,7).

⸻⸻⸻⸻

$\boxed{\text{Finding the Slope:}}\\\\\rightarrow m=\frac{7-5}{8-3}\\\\\rightarrow \boxed{m=\frac{2}{5}}$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Find the area of the region bounded by the curves y = sin^-1(x/6), y = 0, and x = 6 obtained by integrating with respect to y. Y

Nezavi [6.7K]

<span>y = sin^-1(x/6), y = 0, and x = 6 so look at this
since x = 6 "(x/6)" would be (6/6)
Hope this helps and mark as brainliest please!</span>

-5/6x-7/30x+1/5x-52 please help me guys cuz imk not good with math

Marina CMI [18]

Answer:

$\frac{-13}{15} x-52$

Step-by-step explanation:

$\frac{-5}{6}x-\frac{7}{30}x+\frac{1}{5}x-52$

$=\frac{-5}{6}x+\frac{-7}{30}x+\frac{1}{5}x+-52$

Combine Like Terms:

$=\frac{-5}{6}x+\frac{-7}{30}x+\frac{1}{5}x+-52$

$=(\frac{-5}{6}x+\frac{-7}{30}x+\frac{1}{5}x)+(-52)$

$=\frac{-13}{15}x+-52$

Therefore, $\frac{-13}{15}x+-52$ will be your final answer.
