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.
If you factor the expression of part A, you will get the expression of part B
the reason is that the perimeter of a rectangle is equal to 2(l+w)
so in the factorization number 2 will be multiplied by the rest of the expression
good luck
