This is something to memorize
y = r*sin(theta)
so if y = 2, then
2 = r*sin(theta)
Divide both sides by sin(theta) to get
r = 2/sin(theta)
r = 2csc(theta)
Answer:
x > 90, C
Step-by-step explanation:
20 + 2 < x / 3 - 8
x / 3 - 8 > 22
x / 3 > 30
x > 90
Answer:
∠F ≈ 53°
General Formulas and Concepts:
<u>Trigonometry</u>
- sin∅ = opposite over hypotenuse
- sin inverse evaluates "backward" to find the measure angle
Step-by-step explanation:
<u>Step 1: Define</u>
Looking at ∠F
opposite leg of ∠F = ED = 8
hypotenuse = FE = 10
<u>Step 2: Find m∠F</u>
- Substitute: sin∠F = 8/10
- Simplify: sin∠F = 4/5
- Take sin inverse: ∠F = sin⁻¹(4/5)
- Evaluate: ∠F = 53.1301°
- Round: ∠F ≈ 53°
In order to solve this, we need to figure out how much ONE student spends.

dollars per student.
If 10 student spent for lunch, we just have to multiply our number by how much each student spends.
The answer would be 0
Due to it being a horizontal line the slope could have any x coordinates but the y would always be 0
