Answer: x < -2.861353
Step-by-step explanation:
simplify to: 0.69897x <-2
divide both sides by 0.69897
0.69897/0.69897 < -2/0.69897
so the answer is x < -2.861353
If you are rounding to the nearest tenth it would be 8.5.
You can’t round to the nearest ten with 8.546
a = 6.2
Solution:
Given ABC is triangle.
AC = b = 8, BA = c = 11, ∠A = 32.2°
BC = a
To find the length of a:
Law of cosines:






Taking square root on both sides of the equation.
a = 6.1464
a = 6.2
The length of BC is 6.2.
