Question

Us Find the measure of 45. 45 = [?] 510

Answer 1

46 degrees because the way that they line on it is set up cause it’s not 50 degrees or 40 degrees but it’s also close to a 50 degree angle than a 45

Answer 2

ANSWER:

We know that the sum of angles of same sides in parallel lines are supplementary(180°).

So, ∠5 + 51° = 180°

∠5 = 180° - 51°

∠5 = 129°.
