Answer:
30°
Step-by-step explanation:
The area of a triangle given sides a and b and angle C is:
area = (ab × sin C)/2
Here we are given sides a and c, and we are looking for angle B, so we have
area = ac × sin B
12 cm² = [(8 cm)(6 cm)(sin B)]/2
24 = 48sin B
sin B = 0.5
B = 30°

Step-by-step explanation:
32° ... If he is standing 15 feet from the base of the pole, about how tall is the.
Micheal has 40ft of fencing for the rectangular dog run. So the perimeter of the dog run is 40ft.
Perimeter=40ft
The perimeter of a rectangle is:
P=2l+2w
Since we know the length is 5 and the perimeter is 40, we can solve for the width.
P=2l+2w
40=2*(5)+2w
40=10+2w
subtract 10 from both sides
30=2w
divide both sides by 2
15=w
The width of the fence is 15feet.
