Answer:
B, 16.1
Step-by-step explanation:
cos 36 = 13/x
cos 36 × x = 13
x = 13/cos 36

x = 16.068883...
<u>x ≈ 16.1</u>
If you round $4,329.97, $452.28, and $279.34 you would get $4,000, $500, and $300. If you add $452.28 (rounded to $500) twice to $4,329.97 (rounded to $4,000) then you would get $5,234.56 which you would round to $5,000. Then when Alexa withdrawals $279.34 (rounded to $300), you subtract $279.34 from $5,234.56 (rounded to $5,000) and you get $4,955.22 which would be rounded up to $5,000. This proves that Alexa's estimate was reasonable.
Classify the triangle? In other words, state the type of triangle we have here: right, acute or obtuse.
If the triangle is a right triangle, then 48^2+55^2=80^2 by the Pythagorean Theorem. Let's check that out: We get 5329 = 6400, which is false. So this triangle is not a right triangle.
For this to be an obtuse triangle, 48+55 would have to be greater than 80. That's not the case here. Thus, the triangle is ACUTE.
Given : (5x + 8 - 6x) (4 + 2x - 7)
The given question can be written as : (8 - x) (2x - 3)
⇒ 8(2x - 3) - x(2x - 3)
⇒ 16x - 24 - 2x² + 3x
⇒ -2x² + 19x - 24
