Solve the triangle for x. (View the attachment)

A. 39.4(degrees)
B. 46.5(degrees)
C. 94.1(degrees)
D. 105.9(degrees)

Option C

Step-by-step explanation:

By applying cosine rule in the given triangle,

BC² = AB² + AC² - 2(AB)(AC)cosA

(11)² = 8² + 7² - 2(8)(7)cosx

121 = 64 + 49 - 112cos(x)

cos(x) = -

x =

x = 94.1°

Therefore, Option C will be the correct option.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
