Because supplementary angles means mA + mB = 180.
Then subtract 80 from 180 which will get you 100.
So B = 100

This is the part missing:
<span>What is the height of the plane to the nearest meter?
Answer: 559 m.
Explanation:
1) The horizontal distance between the plane and tha atoll makes a right triangle with the height, with the depression angle between the two legs.
2) Therefore, you can use the tangent trigonometric ratio:
tan(10°) = opposite-leg / adyacent-leg = height / horizontal distance
⇒ height = horizontal distance × tan (10°)
⇒ height = 3,172 m × tan(10°) = 559.31 m, which rounded to the nearest m is 559

Complete question :
A zoologist is interested in whether climate affects how high kangaroos can jump. In a random sample of gray kangaroos from an Australian forest, he found the mean jump height was x¯=286 inches with a margin of error of 15 inches.
Construct a confidence interval for the mean jump height of gray kangaroos.
Answer:
(271, 301)
Step-by-step explanation:
Given that:
Mean (x¯) = 286
Margin of Error = 15 inches
The confidence interval :
(Mean - Margin of Error), (mean + margin of error)
(286 - 15), (286 + 15)
(271, 301)
Hence confidence interval equals : (271, 301)
The greatest common factor (GCF) of 40 and 44 is 4.
Explanation:
44 = 4 x 11
40 = 4 x 10
<em>44 + 40 =</em><span> (4 x 11) plus (4 x10) = </span><em>4 times (11+ 10)</em>
