Yes it is because if you multiply 3*3=9
then what you do on top you do on the bottom 10*3=30
Step-by-step explanation:
sinA= BC/AC
= 24/26
= 12/13
cosA= AC/AB
= 10/26
= 5/13
tanA= BC/AC
=24/10
= 12/5
4/9(2n)+4/9(-3)
(4x2/9)n+(4 x -3)/9
(8/9)n -12/9
8/9n-4/3
A is at -8 and C i5 at 5
-8 to 0 is 8 units and 0 to 5 is 5 units.
8 +5 = 13
AC is 13 units long.
