Answer:
lim [(x(2) + 3) × 1/ x(4) ] = 3 × ( + ○○) = + ○○
4a + 7b = 38 -> (1)
9a + 7b = 68 -> (2)
Subtract (1) from (2),
9a - 4a + 7b - 7b = 68 - 38
5a = 30
a = 6
Depends on where you are in the math book but this would be the most simple way.
n= number
sqar(-1) = i
NAP = 180 - NAC - PAT = 180 - 61 - 46 = 119 - 46 = 73 degrees
Just to confirm is it x-5/8 or (x-5)/8
