Daaaaaaaaaammmmm that’s hard
Answer:
the answer is B, complementary angles
Step-by-step explanation:
complementary angles are two angles that add up to 180 degrees
105 + 75 = 180
-8 3/8 = -8 15/40
-12 4/5 = -12 32/40 ,because you had to get a common denominator.
Since you are subtracting from a negative the negative turns into a positive.
-8 15/40 + 12 32/40 = 4 17/40
4 times what equals 9. Well let's do this backwards. 9/4 equals 2.25 or 2 1/4 and 2 1/4 + 3 = 5 1/4. x=5 1/4. 4(5 1/4 - 3) = 9. Hoped I helped!
