Step-by-step explanation:
Find what is x.
the total interior angle of the triangle is 180 degrees
you can use this formula (n-2)180, n is the number of sides of the shape
find what is x:
180-37-22=121
use the sin rule whereby,
(sin 121)/4.357=(sin 22)/a
(sin 121)a=( 4.356 ×(sin22) )
a= (4.356× sin22) /(sin 121)
type in the calculator to find what is a.
Answer:
x=0.9
Step-by-step explanation:
(ask me if u want it)
160 is the first because 1 inches 20 but it says 2 inches so at 40+40+40+40
