- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] cos∅ = adjacent over hypotenuse
Step-by-step explanation:
<u>Step 1: Identify Variables</u>
Angle measure = 58°
Adjacent side of angle = <em>x</em>
Hypotenuse = 9
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [cosine]: cos58° = x/9
- Isolate <em>x</em>: 9cos58° = x
- Evaluate: 4.76927 = x
- Rewrite: x = 4.76927
- Round: x ≈ 4.8
It's 67/100 because a percent is out of 100 which is already simplified
I got 0.999 which is 999/1000
Answer:
x = 3/7
Step-by-step explanation:
Step 1:
6 - 2x = 3 + 5x Equation
Step 2:
6 = 3 + 7x Add 2x on both sides
Step 3:
3 = 7x Subtract 3 on both sides
Answer:
x = 3/7 Divide
