Lines a and b are parallel and lines e and f are parallel.
if m1 = 89°, what is m5

  m∠5 = 91°

Step-by-step explanation:

Linear angles 1 and 2 are supplementary; alternate interior angles 2 and 3 are congruent, as are corresponding angles 3 and 5. Hence angles 1 and 5 are supplementary.

  m∠5 = 180° - m∠1 = 180° -89°

  m∠5 = 91°

correct answer:

i^31 = -i

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
