- [Right Triangles Only] cos∅ = adjacent over hypotenuse
Step-by-step explanation:
<u>Step 1: Define</u>
We are given a right triangle. We can use trig to find the missing side length.
<u>Step 2: Identify Variables</u>
<em>POV from the angle</em>
Angle = 38°
Adjacent Leg = <em>x</em>
Hypotenuse = 21
<u>Step 3: Solve for </u><em><u>x</u></em>
- Substitute [cosine]: cos38° = x/21
- Isolate <em>x</em>: 21cos38° = x
- Evaluate: 16.5482 = x
- Rewrite: x = 16.5482
- Round: x ≈ 16.5

Step-by-step explanation:
Answer:
2y -6
Step-by-step explanation:
5y-3(y + 2)
Distribute
5y -3y - 6
Combine like terms
2y -6
First, you have to make sure that two fractions have the same denominator. he best way to do that is:
For Example: 4 7 8 7
---- + ----- = ----- + -----
10 20 20 20
Then, just add or subtract the numerators and you got your answer.
Boom.
