Multiply the divisor by as many 10's as necessary until we get a whole number. Remember to multiply the dividend by the same number of 10's
Answer:
1. We already have the measure of the hypotenuse and one out of two acute angle, therefore:
sin53° = x/45 => x = sin53° · 45 ≈35.94
2. We already have one out of two legs of the triangle and one acute angle so we know that:
tan27° = 48/x => x = 48/tan27° ≈ 94.21
Answer:
About 4.2 ft
Explanation:
The area of the traingle can be calculated in two ways.

where width = 4.4 ft and length = 13.6 ft.
Putting in the values for width and length gives

The other way that the area can be calculated is

where height = vertical length and base = 14.3 ft; therefore.

This must equal the area of the triangle we found above; therefore,


dividing both sides by 7.15 gives


which is our answer!
