  • [Right Triangles Only] SOHCAHTOA
  • [Right Triangles Only] cosθ = adjacent over hypotenuse
  • Inverse Trig

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

Angle θ = ?

Adjacent Leg = 13

Hypotenuse = 20

<u>Step 2: Find Angle</u>

  1. Substitute in variables [cosine]:                                                                   cosθ = 13/20
  2. Inverse Trig:                                                                                                    θ = cos⁻¹(13/20)
  3. Evaluate:                                                                                                         θ = 49.4584°

Nostrana [21]

Answer:

$6.72

Step-by-step explanation:

The store is selling lemons at $0.56 each. Each lemon yields about 2 tablespoons of juice.How much will it cost to buy enough lemons to make three  9-inch lemon pies, each requiring half a cup of lemon juice?

1 cup = 16 table spoon of juice

half a cup =  8 table spoon of juice

1 pie require half a cup of lemon juice. so 1 pie requires 8 tablespoon of lemon juice

Each lemon yields about 2 tablespoons of juice

2 times 4 = 8

So 4 lemon needed to make a pie

cost of 1 lemon = 0.56

cost of 4 lemons = 0.56 \cdot 4=2.24

cost of lemon for making 3 pie= 3 \cdot 2.24=6.72
