Z1 and z2 are complementary angels given m z1= 12°, find mZ2.
m2

Sum of two angles that are complementary = 90°

m∠1 + m∠2 = 90°

Given :

m∠1 = 12°

Then :-

answer: the answer for that is 22/3

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
