Using relations in a right triangle, considering c as the hypotenuse, we have that the length of side A is: 
<h3>What are the relations in a right triangle?</h3>
The relations in a right triangle are given as follows:
- The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.
- The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.
- The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.
From the information given, we can build the following relation:
cos(A) = a/c.

Answer:
10-u
Step-by-step explanation:
The slope is 7. whatever number is next to x is the slope. if there is no x then it is a horizontal or vertical line.
Answer:
1st answer choice- You do not have enough jars because 20 jars will only hold 35 cups of applesauce.
Step-by-step explanation:
So 1.75 cups of applesauce fits in a jar. You have 20 jars so you multiply the cups of applesauce that can fit in the jar by how many jars you have. It will look like this: 1.75x20=? Now you multiply them and you get 35 which is how many cups of applesauce 20 jars will hold. You will have 5 cups of applesauce left over that cannot be transformed into a jar.
If you can please make my answer the brainliest that would be much appreciated. Thanks!
