Answer:
In fact, the AB could be calculated in a quickest way, using Pythagorean theorem. In here, we try to use the property of trigonometry to work out AB.
Before applying trigonometry, in this right triangle we can calculate the remaining angle C:
C = 180 - 90 - A = 180 - 90 - 53.13 = 36.87 deg
We can use cosine formula, but here we use the sine formula for the sake of convenience. We have:
sine(angle measure) = ratio of opposite side over hypotenuse
In detail, sineC = AB/BC
Then, we have: AB = BC x sineC = 15 x sin(36.87 deg) = 9.000002 = ~9 ft
Hope this helps!

I believe the answer is 1 because the line is negative and has a slope of 1/2 so -1/2 and it crosses at 8
Answer:
96
Step-by-step explanation:
First, the total area is base * height, which is 12*12=144. Next, we subtract the unshaded area, which is 6*8=48. 144-48=96, which is your answer
Since the circumference meaning the whole line is 22 centimeters long then the radius would be half of that...sooo....22/2=11. The radius for N is 11cm...hope it helps :)
A positive number divided by a negative number gives you a negative number for example 12 is positive but the three is negative so our answer has to be negative
