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:
Step-by-step explanation:
This is a compound inequality that basically states that the X value is greater than or equal to -5, but less than or equal to -1. It is inclusive, because it includes both numbers and therefore should have an equal to sign () instead of just less than or greater than ( < or >).
Answer:
f(4) = -18
Step-by-step explanation:
f(x) = -5x + 2
f(4) = -5(4) + 2 = -20 + 2 = -18
Answer:
13Ya is the answers for the question
Step-by-step explanation:
please mark me as brainlest
Number 3.
opens up
vertex (1,2)
idk maybe because it is on the right side. its positive
number 4.
opens up as well
Vertex (-2,0)
no because it is negative and on the left. Idk just a guess for this one
