A. y = 8 − 7x<br> B. y = 7x + 8<br> C. y = 7x − 8<br> D. y = 8x − 7

Answer:

I'm getting

y=-7x+8

The 7 is negative for me..You should maybe try yourself too and see what you get I might have made a mistake

Step-by-step explanation:

I'm guessing you live somewhere in the U.S. so I'll use the equation you use there

Equation:

$y = mx + b$

$m = \frac{y1 - y2}{x1 - x2}$

first pick two points

I'll pick (0,8) and (1,1)

$m = \frac{8 - 1}{0 - 1} = \frac{7}{ - 1 } = - 7$

this means that the slope is -7

So far the equation will look like this

$y = - 7x + b$

to get b pick one point, I'll pick (0,8) and replace y and x

$8 = - 7 \times 0 + b$

when you solve this you'll get b

$b = 8$

So the equation will look this

$y = - 7x + 8$

ABC is a right triangle with right angle at ∠B.

My name is Ann [436]

We have to calculate AC ( hypotenuse ):
AC² = 29² + 28²
AC² = 841 + 1444
AC² = 2285
AC = √2285
AC = 47.8
And for the angle C:
cos C = Adjacent / Hypotenuse
cos C = 38 / 47.8
cos C = 0.794979
∠ C = cos ^(-1) 0.794979
∠ C = 37.35° ≈ 37°
Answer: ∠ C = 37°.
