16 divided by 21 is your answer
Answer:
1.10231131
Step-by-step explanation:
To solve the value of x we use the sine rule that states.
a/sinA = b/sinB = c/sinC
Where a, b, and c are the opposite sides of angle A, B. and C respectively.
x/sin60 = 7/sin80
x =(7sin60)/sin80
= 6.062/0.9848
=6.155696691
To 3 significant figures the answer is 6.16
