Answer:
a - 8.5ft
Step-by-step explanation:
() Using trig ratio
sin(45) = x/12
12 * sin(45) = x
x = 8.5
() Using Pythagorean theorem
*special right triangle*
Since x *
= 12
to find the legs
x =
x = 8.5
For this problem, all you need to do is find the three #'s that add up to 156.
So, lets look at the answers and add them up.
A. 50, 52, 54
50 + 52 + 54 = 156
B. 51,52,53
51 + 52 + 53 = 156
C. 49,50,51
49 + 50 + 51 = 150
D. 49,51,53
49 + 51 + 53 = 153
We get the answers (50,52,54) and (51,52,53)
Now, consecutive numbers are numbers that in order, like 1,2,3.
Therefore, the answer is (51,52,53)
The area is 32 because l x w is the formula of area, and 8 x 4 = 32.
