Answer:
let angle A=x
B=33
angle C=18
the sum of all the angles in a triangle
is 180
now,
A+B+C=180
x+33+18=180
x+51=180
x=180-51
x=129

Answer:
Given
A - B = 33
A = 33 + B
B - C = 18
-C = 18 - B
C = - 18 + B
NOW USING ANGLE SUM PROPERTY
A + B + C = 180
=> 33 + B + B + - 18 + B = 180
=> 15 + 3B =180
=> 3B = 180 - 15 = 165
=> B = 165/3 = 55
THEN A = 55 + 33
A = 88
