Answer:
-4/5
Step-by-step explanation:
When you divide -4 from 5 you get -0.80
95-55 is the simpliest form
a = 56
given 28 =
a
multiply both sides by 2 to eliminate the fraction
56 = a
As a check
× 56 = 28 ← True
We have that
cos(alfa)=0.2546
arc cos (0.2546)=75.2501---------- > 75.25°
the answer is 75.25°
