You need to isolate the variable <em>h</em>. 

1) Subtract both sides by 2. 

-4h + 2 = 18
-4h + 2 - 2 = 18 - 2
-4h = 16

2) Divide both sides by -4 (the coefficient). 
(-4h) / -4 = 16 / -4
h = -4

As you can see, angle 5 and angle 6 are supplementary.  And angle 5 and angle 3 are congruent because they are alternate interior angles.  

So it will be
x+2 = 180- x+3 
                         move x over from the right to the left
2x+2 = 183
                         move 2 over from the left to the right
2x = 181
                          divide by 2
x= 90.5

and angle 3 and angle 1 are vertical angles so they are congruent.  Using the angle 3 formula to solve for the answer:

90.5+3 =93.5

When angles are congruent, their measures are congruent, therefore, measure of angle 1 is 93.5

I need help on this question for math
Ganezh [65]

Answer:

y = -12

Step-by-step explanation:

any equation with only an x or y value present will either be a vertical or horizontal line. Because the y axis is vertical, a line that is present on y=-12 will sit on y=-12 forever, and therefore be a horizontal line

Find the distance from point M to point N on the graph shown. Round your answer to
Anestetic [448]

Answer:

3. 8.60 units

Step-by-step explanation:

Distance from point M(-2, 4) to point N(5, -1) can be calculated using the distance formula, d = \sqrt{(x_{2}  - x_1)^2 + (y_2 - y_1)^2}

M(-2, 4) => (x1, y1)

N(5, -1) => (x2, y2)

Plug in the values into the formula

d = \sqrt{(5 - (-2))^2 + (-1 - 4)^2}

d = \sqrt{(7)^2 + (-5)^2}

d = \sqrt{49 + 25}

d = \sqrt{74}

d = 8.60 units
