Answer:
2.69 approximately 3
Step-by-step explanation:
53⁰+80⁰+A=180⁰(sum of angles on a triangle)
133⁰+A=180
A=180-133
A=47⁰
using sine rule
2/sin 47 = b/sin 80
b sin47 = 2 sin 80
b= 1.9696/0.7314
b=2.69 approximately 3
5x + y = -48
(y + 3)/(x + 9) =m
=> y + 3 = -5x -45
=> 5x + y + 48 = 0
About 9% or 0.09
The answer is: 2(5a + 3)
hope this helps :)
