Given the points below, find the distance from X to Y. Round to the nearest hundredth.

X(-9,2) and Y(5, -4)

We can use the distance formula to find the distance from X to Y:

d = √((x2 - x1)^2 + (y2 - y1)^2)

Plugging in the given coordinates:

d = √((5 - (-9))^2 + (-4 - 2)^2)
d = √((14)^2 + (-6)^2)
d = √(196 + 36)
d = √232
d ≈ 15.23

So the distance from X to Y is approximately 15.23.
<1 and <2 are supplementary angles. m<1 is 2y+12 and the m<2 is 8y+8. Find m<2.
If angles 1 and 2 are supplementary, their measures add up to 180 degrees.

So, we have the equation:

m<1 + m<2 = 180

Plugging in the given measures:

2y + 12 + 8y + 8 = 180

Combining like terms:

10y + 20 = 180

Subtracting 20 from both sides:

10y = 160

Dividing both sides by 10:

y = 16

Now that we have the value of y, we can find the measure of angle 2:

m<2 = 8y + 8
m<2 = 8(16) + 8
m<2 = 128 + 8
m<2 = 136

Therefore, the measure of angle 2 is 136 degrees.
