<h3>
Answer: B. 26</h3>
============================================
Use law of cosines to find angle A
a^2 = b^2 + c^2 - 2*b*c*cos(A)
9^2 = 6^2 + 14^2 - 2*6*14*cos(A)
81 = 36 + 196 - 168*cos(A)
81 = 232 - 168*cos(A)
81 - 232 = -168*cos(A)
-151 = -168*cos(A)
-168*cos(A) = -151
cos(A) = (-151)/(-168)
cos(A) = 0.8988095
A = arccos(0.8988095)
A = 25.9979801
A = 26 degrees approximately
Answer:
A- l-0.13l
Step-by-step explanation:
l-0.14l is the same as 0.14
l0.13l is the same as 0.13
l-0.18l is the same as 0.18
l-0.2l is the same as 0.2
l14l is the same as 14
The only value that is less that 0.14 is 0.13, making A the correct answer.
Step-by-step explanation:
Ace:
15800 x (-2/100) = -316
15800 - 316 = 15485
Beta:
17425 x (-3/100) = -522.75
17425 - 522.75 = 16902.25
Carro:
21280 x (-1.5/100) = -319.2
21280 - 319.2 = 20960.8
Delta:
24172 x (-1.8/100) = -435.096
24172 - 435.096 = 23736.90
