Find the missing side

4) d

5) a

Step-by-step explanation:

4)

Well we know we use sine when we need or have the hypotenuse or opposite side length.

X in this case is the opposite side length so.

Sin59=x/17

x=17sin(59)

x=14.5718

So the answer is d.

5)

We have the adjacent side length and we need opposite side length so use tan

tan(53)=x/12

x=12tan(53)

x=15.9245

Thus answer is a

$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)
