Answer:

<h2>22</h2>

Step-by-step explanation:

f(-2) means that the "x" variable in the equation can be substituted for -2

So, we have

-5(-2) + 12

This equals 10 + 12 = 22

A roofer leaned a 16 foot ladder against a house if the base of the ladder is 5 feet from the house how high up the house does t
valkas [14]

Answer:

15.2 feet

Step-by-step explanation:

We use Pythagorean Theorem to find the height.

The hypotenuse of the formed triangle =  length of ladder = 16 feet

base = 5 feet

let h = height of house

16 ^2 = 5^2  +  h^2

256 = 25 + h^2

231 = h^2

h = root(231) = 15.1986 feet

Suppose that m∠MKN = 55°. What is m∠MCN?<br> !please no absurd answers!
Elena L [17]

Answer:

angle M and N are right angles

we can draw a line joining M and N  

so we’d have a triangle MNC AND KMN

both MNC AND KMN BECOME ISOSCELES TRIANGLES

so since we have 55 degrees for angle MKN. We have to find the other 2

180-55=125

now divide by 2 to get 62.5 for each of the remaining sides of triangle KMN

now to find the sides of triangle MNC

90-62.5= 27.5

27.5*2= 55

180-55=125=angle C

(sorry, it’s complex)
