Three of the angles of a quadrilateral are 90 , 156 and 28 . what is the size of the 4th angle?

anyanavicka [17]

The sum of the sides of a quadrilateral is equal to 360º.
x= 4th angle measurement

We have the following equation:

90+156+28+x=360
x=360-90-156-28
x=86

Answer: the size of the 4th angle would be 86º.

Fill in what’s missing from the chart. Remember, graphing means to plot the values in your table.

Delicious77 [7]

Answer:

(for the second one)

y = 4x + 10

solution:

so first you have to find the slope, there is an equation for it. it is y2 - y1/ x2 - x1 or just y1 - y2/ x1 - x2 . so input the easiest points. id say f(0) and f(1)

so it will look like

2 - 6/0 - 1

-4/-1

so you can now write the equation as

y = 4x + b

now you have to find the y-intercept so input a point. i dont think you should input a point you used to find the slope because you could have made a mistake calculating so lets input f(2)

sooo

18 = 4(2) + b

18 = 8 + b

b = 10

so the function for the second one is y = 4x + 10
