Due Tomorrow: answer question 3 using steps

Step-by-step explanation:

Picture is quite fuzzy so I will ASSUME that the triangle has inner angles of 100° and 34°

This means the unlabeled angle is 180 - 100 - 34 = 46°

Using law of sines.

a/sin46 = 12/sin34

a = 12sin46/sin34 = 15.17415...

round as appropriate, probably two significant digits

a = 15

If I did not guess the numbers in the photo correctly, just use the same technique to arrive at a better solution.

0.32

step-by-step explanation:

2.24/7

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
