Answer:
B) 0.85
Step-by-step explanation:
By definition, complementary angles add to 90 degrees.
The given angle 58 degrees is complementary to 90-58 = 32 degrees. The two angles 58 and 32 add to 90.
Therefore, cos(32) = 0.848 = 0.85
Answer: 4). 35,56,89

Please show all of the expressions.
4(2x)=8x
4(3)=12
8x+12=75
-12
8x=63/8
x=7.89
