To find the slope (m) of the equation, you use the slope formula:
Now you plug in the points into the formula
Now you need to find b, to do so you plug in either of the points into the equation.
0 = b
The equation of the line is:
Answer:
x = 15
WX = 34
Step-by-step explanation:
Part 1:
We know that arc AB and AC have to be equal because the lines splitting off from the center point are congruent to eachother.
Lets start by subtracting 106 from 360, which gives us 254. We know that both of our missing arcs have to add up to equal 254 and we also know that they're congruent. This means we can simply divide 254 by 2 to get 127 and set that equal to our 10x - 23.
10x - 23 = 127
Get x by itself
10x = 150
x = 15
Part 2:
Since we're assuming both XY and XW are tangent we're just going to set them equal to eachother.
7x - 29 = 2x + 16
Get your Xs on one side and your constants on the other.
5x = 45
Divide
x = 9
Plug in your x
7(9) - 29
63 - 29
WX = 34
Answer:
Any measure 7-17 (non-inclusive).
Step-by-step explanation:
12-5 = 7
12+5 = 17
The length of the third side of a triangle must be between the measures of the difference and the sum of the other two sides.
156x - 220x = 16y
64x = 16y
4x = y
