Jean bought a 1980 snow thrower on the installment plan. The installment agreement included a 10% down payment and 18 monthly payments of 118 each. what is the total amount of the monthly payments

no one knows lol

step-by-step explanation:

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
