b = 35

Step-by-step explanation:

a and b make a right angle

a+b = 90

55 + b = 90

subtract 55 from each side

55-55 +b = 90-55

b = 35

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
