A painter is placing a ladder to reach the third story window, which is 12 feet above the ground and makes an angle of 80 degree

mash [69]

We know that
tan ∅=opposite side angle ∅/adjacent side angle ∅
adjacent side angle ∅=opposite side angle/tan ∅

in this problem
see the attached figure to better understand the problem
angle ∅=80°
opposite side angle ∅=12 ft (AB)
adjacent side angle ∅=? (AC)
adjacent side angle ∅=12/tan 80°------> 2.12 ft

the answer is
2.12 ft

Exercise 59 use the table to evaluate the given expressions

Arlecino [84]

Answer: f(0) = 5.5 f(2) = 3.7

<u>Step-by-step explanation:</u>

$\begin {array}{c|c|c|c|c|c}x&0&1&2&3&4\\ f(x)&5.5&4.3&3.7&2.5&1.9\\\end{array}$

When x = 0, f(x) = 5.5 <em>In other words, f(0) = 5.5</em>

When x = 2, f(x) = 3.7 <em>In other words, f(2) = 3.7</em>

Can a quadrilateral be a rhombus ?

koban [17]

Yes it can. It doesn't <em>have to be</em>, but it can be without too much trouble.

In fact, ALL rhombuses are quadrilaterals.

Find the unknown side length, x. Write your answer in simplest radical form.

Otrada [13]

Answer:

B (5 sqrt10)

Step-by-step explanation:

If the hypotenuse is 17, and a leg is 8, that makes the other leg equal to sqrt((17^2)-(8^2)) = sqrt(289-64) = sqrt(225) = 15.

Because you subtract 3 from the leg with length 8, that makes the smaller triangles leg 5. That makes the hypotenuse sqrt(5^2 + 15^2) = 5sqrt10

I'm guessing you typoed for B and meant 5sqrt10, so the answer is B
