varies directly as
.
Therefore, this is a direct variation.
Answer:
Step-by-step explanation:
<u>We know that:</u>
- Angles ∠A and ∠B are 28° and 37°.
<u>We don't know:</u>
<u>So, we do this:</u>
- Add the 180°
- Solve the equation 180 - 28 - 37
<u>Solve:</u>
Angle ∠C is 115°.
Hi!
When you add a negative number, you really just subtract it. So let's solve this.
Convert the mixed numbers into improper fractions.

Solve
434 - 351 = 83

The sign of this fraction is positive

Answer:
B -9/7
Step-by-step explanation:
We need to find a number between
-3 1/3 < x < -4/5
We want a number smaller than between -3 1/3 and -.8
Looking at the choices
-9/7 = - (7/7 + 2/7) = -(1+2/7) = -1 2/7
That is between -3 1/3 and -4/5
The cosine ratio is adjacent leg divided by the hypotenuse.
The hypotenuse in a right triangle is the longest side and it is opposite the right angle.
An adjacent leg is the side that has an endpoint that is at the vertex of the angle and the other endpoint is at the vertex of the right angle.
cos A =
