Answer:
59.0°
Step-by-step explanation:
Many triangle solvers are available for your phone, tablet, or browser. The attachments show the input and output of one of them.
___
You can use the law of cosines to compute the result yourself.
b^2 = a^2 + c^2 - 2ac·cos(B)
cos(B) = (a^2 +c^2 -b^2)/(2ac) = (22^2 +18^2 -20^2)/(2·22·18) = 408/792
B = arccos(408/792) ≈ 58.9924° ≈ 59.0°
Answer:
12 units³
Step-by-step explanation:
original volume of box = 120 units³
If the box if it is scaled down by a factor of 1/10, then we multiply the original volume by 1/10:
120 x (1/10) = 120 ÷ 10 = 12 units³

Answer:
D. 58
Step-by-step explanation:
If the sample size is larger than 30, the sample can be approximated as normally distributed, even if the population it came from isn't.
The area of a rhombus is 1/2 times the lengths of the diagonals
A = (1/2)(AC)(BD)
Since the diagonals bisect each other, and ed = 8, BD must be 16. Substituting in this for BD and the given area (168) we get the following:
168 = (1/2)(AC)16
168 = 8(AC)
21 = AC
