Option D

-4>-7

C is correct but same in case for D

2.5<3

-2.5>-3

Hence D is wrong

Find M<br> A. 17<br> B. 16<br> C. 18<br> D. 20

mixas84 [53]

Answer:

A. 17

Step-by-step explanation:

using the cosine rule (also see attached for reference):

AB² = BC² + AC² - 2·AC·BC cos C

2·AC·BC cos C = BC² + AC² - AB²

Given that AC = 18, AB = 12 and BC = 18, substituting these into the formula

2(18)(28) cos C = 28² + 18² - 12²

1008 cos C = 964

cos C = 964/1008

cos C = 0.9563

C = cos⁻¹ 0.9563

C = 16.99 ( = 17° rounded to nearest degree)

The teacher passed out math books. The length is 10 inches and the width is 8 inches. What is the perimeter of each book?

loris [4]

Books are rectangles so that means that opposite sides are equal so if one side is 10 inches then so is the opposite side. same for the 8. the perimeter is the amount around the rectangle so you must add all sides together to find it so

10in+10in+8in+8in= 36in
