Aright triangle has side lengths 7, 24, and 25 as shown below.
use these lengths to find tan b, sin b, and cos b.
tan b
sinb =
lnb
cosb =

see below in bold.

step-by-step explanation:

7 and 24 are the lengths of the 2 legs   and 25 is the length of the hypotenuse.

assuming   angle b is opposite the leg of length 7:

tan b = opposite/ adjacent side = 7/24.

sin b = opposite / hypotenuse = 7/25

cos b = adjacent /hypotenuse = 24/25.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
