Answer:
AC = 12.5 cm
Step-by-step explanation:
use cosine law c^2 = a^2 + b^2 − 2ab cos(C)
c^2 = 6^2 + 10^2 - 2(6)(10)(cosin100)
c^2 = 156.84
c= √156.84
c= 12.5 cm
The cosine rule is used when we are given either three sides or two sides and the included angle.
Answer:
2134
Step-by-step explanation:
beacuse that is the wright answer
If you would like to solve 2 * (7 - x) = 3 * (x + 3), you can do this using the following steps:
2 * (7 - x) = 3 * (x + 3<span>)
</span>2 * 7 - 2 * x = 3 * x + 3 * 3
14 - 2 * x = 3 * x + 9
14 - 9 = 3 * x + 2 * x
5 = 5 * x
x = 1
The correct result would be x = 1.
