Answer:

A=52.8 miles (approximately)

Step-by-step explanation:

We can assume that this triangle is not a right angle, therefore we cannot use Pythagorean theorem. Let's use the Law of Sines:

$\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}$

Where A is unknown, a=28 miles, b=32 miles, B=87°

Therefore by law of sines we have:

$\frac{sin(A)}{28} =\frac{sin(87)}{32} \\$

By multiplying 28 to Isolate sin(A) we have:

$sin(A)=\frac{28*sin(87)}{32}$

To cancel out sine on the right, we must multiply both by the inverse sine and so:

$A=sin^{-1}(\frac{28*sin(87)}{32})=52.7658\\ \\A=52.8mi$

The length of a rectangle is 5ft longer than twice the width. if the perimeter is 70 ft. find the length and width of the rectan

vlada-n [284]

Let the width = x then we have that length = 2x + 5 and also that:
x + x + 2x + 5 + 2x + 5 = 70
6x + 10 = 70
6x = 60
x = 10

Therefore width = 10ft and length = 25ft

If the weight of a package is multiplied by 4/5 the result is 30 pounds. Find the weight of the package

Archy [21]

Answer:

weight * (4 / 5) = 30

weight * .8 = 30

weight = 30 / .8

weight = 37.5 pounds
