Answer: y = 7
Step-by-step explanation:
√8y - 7 = 7
(√8y - 7)^2 = (7)^2
8y - 7 = 49
+7. +7
8y = 56
Y = 7
Since angles EFA, AFB, and BFC lie on a straight line, then they must add up to 180° (angle sum of a straight line)
So, 7x + 4 + 8x + 6 + 6x + 2 = 180
21x + 12 = 180
21x = 168
x = 8
111+496= 607
1/10 + 1/10 = 2/10
607 + 2/10 = 607 and 2/10
But if youre just doing an approximate answer then...
111 = 110
496 = 500
So it would be 610
You can make 2/10 to 1/5 but that wouldnt be approx.
Your answer should be 610 and 2/10
