Answer:
∠ A ≈ 16.67°
Step-by-step explanation:
Using the Sine rule in Δ ABC
=
, substitute values
=
( cross- multiply )
16 sinA = 8 sin35° ( divide both sides by 16 )
sin A =
, thus
∠ A =
(
) ≈ 16.67° ( to 2 dec. places )
-8 - 5n = 64 + 3n
+5n +5n add 5n to both sides, 5n's cancel out on the left.
______________
-8 = 64 + 8n
-64 -64 subtract 64 on both sides, 64's cancel out on the right.
______________
-72 = 8n
___ ___ divide 8 on both sides, 8's cancel out from the right.

Tricky question. This isn't a ratio question even though it seems like one.
First divide 7 by 4.

With more men, the hours taken to repair a road will be even shorter.
So next divide 6 by 1.75.

Answer : It'll take 3.43 hours to do the job if they work at the same rate.
