Answer:
- B. √96 in, √24 in, √120 in
Step-by-step explanation:
Use Pythagorean to verify:
The square of the two smallest lengths is same as the square of the largest side
- A. 108 + 72 = 180 ≠ 192, no
- B. 96 + 24 = 120, yes
- C. 132 - 24 = 108 ≠ 120, no
- D. 168 - 72 = 96 ≠ 84, no
Correct choice is B
Answer:
no!
Step-by-step explanation:
19 1/2 = 39/2
39/2 divided by 3/4
Keep Change Flip
<u>39</u> * <u>4</u> =
2 3
simplify before you multiply
<u>13</u> * <u>2</u> = 26
1 1

Answer: D.
Step-by-step explanation:
the ratio of 12/4 is the same as 3
Answer: A. 31.5
Step-by-step explanation:
Using law of cosine because it is side angle side
a=16
b=21
angle = 116
c^2=a^2+b^2-2ab cosC, let C be the angle given
c^2=(21)^2+(16)^2-2(16)(21) cos(116)
c^2=441+256-672 cos(116)
i used a ti-89 and answered the right side and got
(you can find a ti-89 simulator online, but for problems like this make sure it is in degree mode)
991.585
c^2=991.585
take square root of both sides
=31.4894, which if you round it up it would be 31.5, so the answer would be A
therefore:
a=16
b=21
c=31.5
The answer for this is less than 887
