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
Number 2 is 990 because the numbers are 9, 10, and 11.
5/8th is shaded
5 shaded out of 8 circles total
I don't know the answer but you have to add 333.34 3 times or multiply it 3 times. I don't know the 2nd question.
