What equation can be used to solve for c? c = (5)cos(35o) c = 5/cos(350), c = (5)sin(35o) c =

c = 6.1 in

Option B.

Step-by-step explanation:

Your full question can be found in the image below

Since we are dealing with a right triangle, we can use a great number of properties,

We know that

cos(35°)  = Adj cathetus / Hypotenuse

cos(35°)  = 5 in / c

c = 5 in / cos(35°)

Option B.

c = 5 in / 0.82

c = 6.1 in

a. she will receive a refund of $278.

step-by-step explanation:

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
