Answer:

k = 140°

Step-by-step explanation:

The sum of the interior angles of any triangle = 180°.

64° + 76° + x = 180°

x = 40°

40° + k = 180° because they are supplementary angles

k = 140°

Answer:

k = 140°

Step-by-step explanation:

The sum of the interior angles of any triangle = 180°.

64° + 76° + x = 180°

x = 40°

40° + k = 180°

k = 140°

Please help i don’t know what answers apply

Answers are B, C, and D

If Q = 33, then the two slopes are both 33. As long as the y intercepts are different, then the two lines will be parallel leading to no intersections. No intersections means no solutions.

Note: Choice A leads to infinitely many solutions as we'll have identical copies of the same expression on each side (33x+25 = 33x+25). This is why we can rule choice A out.

Answer:

I’m guessing 108 or 165

Step-by-step explanation:

because if 45/500 if you double that it would be 90/1000. after 200 is about half of 500 so 45 divided by 2 is 22.5. yeah i’m like no help sorry
