Answer:
10 in
Step-by-step explanation:
There are two ways to work this problem, and they give different answers. The reason for that is that <em>the data shown in the diagram is not consistent</em>.
<u>Method 1</u>
Use the area to determine the base length. The area formula is ...
A = (1/2)bh
20 in^2 = (1/2)(b)(4 in)
(20 in^2)/(2 in) = b = 10 in
The missing side dimension is 10 inches.

<u>Method 2</u>
Use the Pythagorean theorem to find the parts of the base, then add them up.
Left of the "?" we have ...
left^2 +4^ = 6^
left^2 = 36 -16 = 20
left = √20 = 2√5
Right of the "?" we have ...
right^2 +4^2 = 8^2
right^2 = 64 -16 = 48
right = √48 = 4√3
So, the base length is ...
base = left + right = 2√5 +4√3
base ≈ 11.400 in
The missing side dimension is 11.4 inches. (The area is 22.8 in^2.)
Answer:
i think it a or b but i might be wrong
Step-by-step explanation:
sry if it is wrong tho
468/(22+17)=12 hours
Bicycles will meets after 12 hours
The answer:
the full question is, <span>Given that L is equidistant from M and K, find m KLN
as we see on the figure
m</span>KLN ≈ mMLN, so 33 = 2y + 23
so 33 - 23 = 2y, 10° = 2y, and then y= 10/2 = 5°
finally, we can tell that mKLN ≈2(5) + 23 = 33°
the answer is <span>B. 33</span>
