Which equation correctly uses the law of cosines to
solve for the length s?
92 = 52 + 102 - 2(s)(10) cos(100°)
9 = s + 10 - 2(s)(10)cos(100)
102 = 52 + 100 – 2(s)(10)cos(100)
S2 = 92 + 102 - 2(9)(10)cos(100)

Ответ:
fourth option
Step-by-step explanation:
Using the Law of Cosines in Δ STU to find s
s² = t² + u² - 2us cosS
where t = 9, u = 10 and S = 100° , thus
s² = 9² + 10² - 2(9)(10)cos100°
Ответ:
6528 square inches
Step-by-step explanation:
First, add the 17 inches and the 4 inches together to get the total side length for the bigger cube and you should get 21 inches. Then, multiply all the sides of the bigger cube together (24*12*21). Finally, do the same thing with the smaller cube and add both volumes together.
