<u>Short answer</u> = C) 8/10
<u>Working :</u>
Tan A = 8/6 = Opposite / AdjacentOpposite = 8 units
Adjacent = 6 units
Hypotenuse =

=
= 10 units
Cos B = Adjacent/ Hypotenuse
∴ cos B= 8/10

Answer:
t =
Step-by-step explanation:
First, you need to complete the -3 + 1 and then expand the brackets
-3 + 1 = -2
7t -2 - (-2) = -3(1 - 3t)
Now expant the -3(1 - 3t) bracket
-3 * 1 = -3
-3 * -3t = 9t
7t - 2 - -2 = 9t - 3
The two negatives turn positive:
7t - 2 + 2 = 9t - 3
7t = 9t - 3
Move the -3 over to the oposite side, and also move the +7t over to the +9t, making it a negative:
3 = 9t - 7t
3 = 2t
Divide both sides by 2:
t =
So the value of t is
