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.
1) you add the variables in the bracket
(4+5)÷3×4
9÷3×4
2) you multiply 3 by 4
9÷3×4
9÷12
3) now you divide 9 by 12
9÷12
=0.75
