Step-by-step explanation:
Picture is blurr. kindly upload clear pic
Fourth and fifth ones are right
Below.
a = 37 degrees ( vertical angle to 37 )
c = 180 - 37 = 143 degrees (adjacent angles add up to 180).
b = 180 - 37 - 109 = 34 degrees (angles in a triangle sum to 180 degrees).
C= 10+30x
X=9 here so
C= 20+30(9)
So
C=290
