Very confused, do not understand how to complete these 2 questions properly.

11) tan(7x+3) = OE/OJ

7x+3=arctan(OE/OJ)=45

x=6

12) a) x = 40

<ajq = <acq (base angles of isosceles triangle)

50+x+90=180

x=40

b) they are congruent triangle, reason HL   (hypotenuse, leg)

aj=ac

aq=qa

right angle equal

$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)
