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:

11.66 which is approximately 12

Step-by-step explanation:

by using Pythagoras method

a^{2}+b^{2}=c^{2}    because c is the hypotenuse  

6^{2}+10^{2}=c^{2}

36+100=c^{2}

136=c^{2}

\sqrt{136}=\sqrt{c}

c=11.66
