I started this one then got busy with other things.
z and 71 deg form a same side interior pattern
they're supplementary angles
sum to 180 degrees
z + 71 = 180
z = 180 - 71
z = 109 degrees
z and x are alternate angles
their measures are the same
z = 109 deg so x = 109 deg
y and 71 deg form adjacent angles which are supplementary
sum to 180 degrees
y = 180 - 71 = 109 deg
x = 109 deg, y = 109 deg, z = 109 deg
Part b
w and 88 form a supplementary pair
they add to 180 deg
w = 180 - 88 = 92 deg
v and 101 deg are vertical or opposite angles
They are congruent
So v = 101 deg
A /explanation bc I see no reason for the answer to have a - so I believe it’s A sorry if it’s wrong
Answer:
40
Step-by-step explanation:
3x^2 + 8x = 2
3x^2 + 8x - 2 = 0
D = b^2+4ac
D = 8^2+4(3)(-2)
D = 64+(-24)
D = 64-24
D = 40

Answer:
r = 13
Step-by-step explanation:
As the vertically opposite angles are equal,
8r + 6 = 9r - 7
<u>Now you can find the value of r.</u>
8r - 9r = -6 - 7
-r = -13
r = 13
Hope this helps you :-)
