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:
Radius = 9
Step-by-step explanation:
Circumference = 2πr
2πr = 18 ×3.14
2πr = 56.5
6.28r = 56.5
r = 56.5/6.28
r = 9.04 round off , 9
