I'm not sure how you would not use the slope formula to find the slope from the points?
If you did the slope would be 0
Answer: 345
Step-by-step explanation: 1354-574-346=434-89= 345
Answer:
46.7°
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to help you remember the relationships between sides and angles in a right triangle.
<h3>Sine</h3>
Here, the side lengths given are the hypotenuse (11) and the side opposite the angle (8). The mnemonic reminds you the relation involving those sides is ...
Sin = Opposite/Hypotenuse
Applying this to the given triangle, you have ...
sin(x) = 8/11
<h3>Angle</h3>
The angle is found using the inverse sine function. This may be called the sin⁻¹ function on your calculator. It is also referred to as the arcsine function.
x = arcsin(8/11) ≈ 46.658°
x ≈ 46.7°

<em>Additional comment</em>
The attachment shows a calculator making this computation. The angle mode is set to "Degrees", as indicated in the lower left corner.
The time (minutes) vary directly with the number of walls and inversely to the number of people.
m = kw/p, where m = minutes, w = walls, and p = people
60 = 5k/7
420 = 5k
84 = k m = 10(84)/10
m = 84
It takes 84 minutes for 10 people to paint 10 walls.
Answer:
<h2>12</h2>
Step-by-step explanation:
So our equation is:
(7x+5)+(5x+3)+(12x-20) = 276
First remove parenthesis:
7x+5+5x+3+12x-20=276
Combine like terms:
24x-12 = 276
Add 12 on both sides:
24x = 288
Divide:
288/24 = 12
