Answer:

The measure of the angle = <u>43.36°</u>

Step-by-step explanation:

It is required the angle of the question mark, let it = x

So, we have a right triangle.

The opposite of the angle x = 17

And, the adjacent of the angle x = 18

We should know that:

tan x = opposite / adjacent

So, tan x = 17/18

∴ x = tan⁻¹(17/18) ≈ 43.36°

So, The measure of the angle = <u>43.36°</u>

Find f(h(-1))<br> 2<br> -9<br> 11<br> -11
kumpel [21]

Answer:

  (d)  -11

Step-by-step explanation:

Each of the functions is evaluated in the usual way: put the number where the variable is in the expression and simplify.

  h(-1) = -2(-1)² -3(-1) +1 = -2 +3 +1 = 2

  f(2) = (2(2) +7)/(2 -3) = 11/-1 = -11

Then f(h(-1)) is ...

  f(h(-1)) = f(2) = -11

X+5=-12<br><br> Please Help!
qwelly [4]

<u><em>Answer: x=-17 and -17=x. *The answer should be the negative sign.*</em></u>

Step-by-step explanation:

subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.

a-c=b-c

subtract by 5 both sides of an equation.

x+5-5=-12-5

simplify.

12+5=17

17-5=12

17-12=5

x=-17 and -17=x

Hope this helps!

Thanks!

Have a great day!
