Answer:
using cos=adjacent/hypotenuse
Step-by-step explanation:
in this case cos(60)=x/4√3
x=cos(60)*4√3
x=3.46
7/8+(−2/3) divided by 5/6
(7/8 - 2/3)/(5/6)
=(21/24 - 16/24) / (5/6)
= (5/24) / (5/6)
= 5/24 * 6/5
= 6/24
= 1/4

8 zeroes in a trillion
Answer:the answer is A: (0,80)
Step-by-step explanation:
180-2(55)-x=0
180-110-x=0
70-x=0
-x=-70
x=70°
