Step-by-step explanation:

it wants us to find sin a

the opposite of a is 24 and the hypotenuse is 26

so sin A = 24/26

it wants us to find cos a

the adjacent of a is 10 and the hypotenuse is 26

so cos A = 10/26

have a great day :D

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
