Step-by-step explanation:
you know that the overall angle is a right angle (that is what that little square in the corner means) ?
a right angle stands for 90 degrees.
and there you have practically your answer, right ?
angle 1 plus angle 2 are these 90 degrees.
as we know angle 1 = 53 degrees, that leaves only to rest of 90 degrees gut angle 2.
and you know how to get "the rest" ?
subtraction.
90 - 53 = 37 degrees for angle 2
