Find the values of x and y.<br> help please work has to be shown ..
Likurg_2 [28]

Answer:

x = 7 and y = 17

Step-by-step explanation:

16x + 9x + 5 = 180 cuz they are supplementary

25x = 175

x = 7

We also know that 16x + 4y = 180

so 16(7) + 4y = 180, so 4y = 180 - 112, so 4y = 68. y = 17

hope this makes sense

Find the equation for the line that passes through (4, - 8) that has slope - 2. Give your answer in
NNADVOKAT [17]

Answer:

y+8=-2(x-4)

Step-by-step explanation:

point-slope form is y-y1=m(x-x1) where m is the slope, and (x1,y1) is a point.

We are given all of that information:

slope: -2

point: (4,-8)

substitute the numbers into the equation

y--8=-2(x-4)

we can make --8 to positive 8

so:

y+8=-2(x-4)

this is the equation in point-slope form

Hope this helps!

BRAINLIEST ANSWER TO FIRST ANSWERER!!!!!
krok68 [10]

Answer:

Option C \frac{1}{2}(185\°-x\°)=76\°

Step-by-step explanation:

we know that

The measurement of the <u>exterior angle</u> is the semi-difference of the arcs it comprises

so

76\°=\frac{1}{2}(arc\ ST-arc\ XZ)

we have

arc\ ST=185\°

arc\ XZ=x\°

substitute

76\°=\frac{1}{2}(185\°-x\°)

Rewrite

\frac{1}{2}(185\°-x\°)=76\°
