Mathematics

Answer:

I don’t get most of it, but I believe “doubles” means two of the same number added together. For example, 9+9 is a double. I think “doubles +1” means a double and add one. For example, 6+6+1. If I were your sister, I would write “9+9 = 18” for doubles and “6+6+1 = 13” for doubles +1.

I hope I helped!

Can someone double check my work for this problem? I got 38°??
scoundrel [369]
We need to use Law of sine.

sin A/a = sin C/c
sin A/|CB| = sin C/|AB|

sin A/14 = sin(118⁰)/ 20
sin A = (14*sin(118⁰))/ 20

A=arcsin((14*sin(118⁰))/ 20) ≈ 38⁰
