Answer 1. you will need to know population to go hand on hand with how many phones their are, if you don’t you won’t know how many teenagers are alive nor phones
Answer:
Step-by-step explanation:
You can calculate the length of side a using the Cosine Rule:
a^2 = 32.6^2 + 41.4^2 - 2.32.6.42.4 cos pi/6
a^2 = 456.01
a = √456.01
a = 21.35
By the Sine Rule:
32.6 / sin B = 21.35 / sin pi/6
sin B = (32.6 * sin pi/6) / 21.35
sin B = 0.76347
B = 0.869 radians.
C = pi - pi/6 - 0.869 = 1.749 radians.
The answer is D) (-1,0) and (0,6). when you solve by substitution, all you need to do is solve for the variable in one equation and plug the answer into the other equation.
