Answer:
15 and 25
Step-by-step explanation:
the interior angles of a triangle, when added, = 180...so if one angle equals 140, then the other 2 angles have to measure a combined total of 40.
the other 2 angles are in a ratio of 3:5....added = 8
so one angle is 3/8 of 40......3/8 * 40 = 120/8 = 15 <===
the other angle is 5/8 of 40....5/8 * 40 = 200/8 = 25 <==
