Susanne has no money. In order to buy her sister a gift, she borrowed $15 from her mom. When her birthday came, she received $45 dollars. If she repays her mom, how much money will she have?

$30

Step-by-step explanation:

Given data

She borrowed $15 from her mom

Hence she is on -$15

She received $45 dollars

so when she repay $15 her balance will be

= 45-15

=$30

Hence she will save $30

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
