Solve for the given variable

42 degrees

Step-by-step explanation:

Angles in a triangle equal 180

180-(37+90)=53

Angles on a line equal 180

180-53=127

127=3b+1

126=3b

b=42

42 degrees

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
