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:

Step-by-step explanation:
360 / 8
= 45 miles per hour.
Y-6=1/2(x-5) in slope intercept form
y-6=1/2x -5/2. multiply by 2 to remove fractions
2y-12=x-5. write in correct order
x - 2y = -7 standard form
