Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.

x = (65)

20 + 55 + 40 = 115
180 - 115 = 65
Therefore, x = 65

Find the x and y intercepts of the linear equation 2x - 4y = -20

dsp73

Answer:

see explanation↓

Step-by-step explanation:

We are given the following equation of a line:

$2x-4y=-20$

To determine the x-intercept we must set "y = 0":

$2x-4(0)=-20$

$2x=-20$

Now, we divide both sides by 2:

$x=-\frac{20}{2}=-10$

Therefore, the "x" intercept is -10.

To determine the y-intercept we set "x = 0":

$2(0)-4y=-20$

$-4y=-20$

Now, we divide both sides by -4:

$y=\frac{-20}{-4}=5$

Therefore the y-intercept is 5.
