Answer:
(a) 26 degrees
(b) 35 degrees
Step-by-step explanation:
(a) complementary angles add up to 90 degrees, therefore the complementary angle to 64 degrees would be 90 - 64, or 26 degrees.
(b) supplementary angles add up to 180 degrees, therefore the supplementary angle to 145 degrees would be 180 - 145, or 35 degrees.
