- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] tan∅ = opposite over adjacent
Step-by-step explanation:
<u>Step 1: Define</u>
We have a right triangle triangle. We can use trig to find the missing length.
<u>Step 2: Identify Variables</u>
<em>POV from the angle measure</em>
Angle = 64°
Opposite = 13
Adjacent = <em>x</em>
<em />
<u>Step 3: Solve for </u><em><u>x</u></em>
- Substitute: tan64° = 13/x
- Multiply <em>x </em>on both sides: xtan64° = 13
- Isolate <em>x</em>: x = 13/tan64°
- Evaluate: x = 6.34052
Answer: Second option
Explanation: As u can see the fraction is being multiplied 3 times.
<span>Answer:
a manufacturing process has a 70% yield, meaning that 70% of the porducts are acceptable and 30% are defective. If three of the products are randomly selected, find the probability that all of them are acceptable.

Answer:
y=1/3x-3
Step-by-step explanation:
To find slope, use m=y1-y2/x2-x1. I did -4-(-3)/-3-0 to get 1/3. Then plug it and one of the points into y-y1=m(x-m1). y-(-4)=1/3(x-(9-3)). Simplify (isolate y) to get y=1/3x-3.
