Answer:

∠F ≈ 53°

General Formulas and Concepts:

Trigonometry

sin∅ = opposite over hypotenuse
sin inverse evaluates "backward" to find the measure angle

Step-by-step explanation:

Step 1: Define

Looking at ∠F

opposite leg of ∠F = ED = 8

hypotenuse = FE = 10

Step 2: Find m∠F

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°

Answer: The 2/9 should have been simplified to 2/3. Then multiply 1/7 and 2/3 to find the product, 2/21

You have to "simplify" both factors at the same time before moving on to multiplying them.

Step-by-step explanation:

Another way to do this is to multiply straight across 3/7 × 2/9 to get 6/63 then notice that the numerator and denominator are both multiples of 3.

Simplify by dividing numerator and denominator by 3 to get 2/21

Brenna drew a scale drawing of an office building. The scale of the drawing was 1 inch = 1 foot. What scale factor does the draw

DochEvi [55]

Answer:

$\frac{1}{12}$ .

Step-by-step explanation:

Brenna drew a scale drawing of an office building.

The scale of the drawing was 1 inch = 1 foot i.e. 12 inches

Now, the scale factor is defined by the factor by which of length in the original object must be multiplied to get the corresponding length of the drawing.

So, in our case the scale factor is given by $\frac{1}{12}$ . (Answer)
