Since all angles in a triangle must add up to 180, let's create an equation.


angle a + angle b + angle c = 180

35 + angle b + 90 = 180

(the square at angle c represents a right angle, or an angle measuring 90 degrees)

125 + angle b = 180

angle b = 55


Final Answer: (coincidentally) angle B is 55 degrees, choice B
