Answer:

44.5 ft

Step-by-step explanation:

Reference angle = 39°

Opposite = x

Adjacent = 55

Apply trigonometric function TOA:

Tan 39 = Opp/Adj

Tan 39 = x/55

55 × Tan 39 = x

44.5381218 = x

x ≈ 44.5 ft

Use proportion to find the whole 75 is 15% of what number
Iteru [2.4K]

Answer:

500

Step-by-step explanation:

15% * x = 75

(15/100) * x = 75           Multiply both sides by 100/15

(15/100)*(100/15) = 75 * 100/15

x = 7500/15

x = 500

Answer 500

Proportion

15/100 = 75 / x             Cross multiply

15x = 100*75                Combine the right

15x = 7500                   Divide 15

15x/15 = 7500/15

x = 500

Draw and label an example of two parallel lines that are perpendicular to a third line.
lara31 [8.8K]
Euclid used a somewhat different parallel postulate in trying to avoid the notion of the infinite.  He observed that when two parallel lines are intersected by a third line, called a transversal, then if you measure two angles formed by these three lines, on the same side of the transversal and between the parallels, they will add to  (that is, they will be supplementary).  Such angles are called same-side interior angles<span>:</span>
