Answer:

x=5

Step-by-step explanation:

The sum of the angles of a triangle are 180 degrees

The box is a right angle which is 90 degrees

60+6x+90 = 180

Combine like terms

150+6x= 180

Subtract 150 from each side

150-150+6x = 180-150

6x = 30

Divide by 6

6x/6 =30/6

x = 5

Answer:

Step-by-step explanation:

$( \frac{x}{6}) - 10 = 2 \\ ( \frac{x}{6} ) = 2 + 10 \\ \frac{x}{6} = 12 \\ x = 12 \times 6 \\ x = 72$

Answer:

Answer D (the fourth one)

Step-by-step explanation:

First, we need to set up a (y−k)^2=4p(x−h). After plugging in all of your values, you would get (x-5)^2=-4(y-1). Now, we need to solve in terms of y by dividing each side by the factors that don't contain the variable. Your final solution should be $y = -\frac{1}{4}(x - 5^{2}) + 1$
