Answer: We can use equations to represent the measures of the angles described above. One equation might tell us the sum of the angles of the triangle. For example,
X°+145°=180° because there supplementary angles.
X°=35° because 180-145=35°.

100%=20 questions
25%=X questions
X=25%×20=500
X=500/100
X=5
not B=20-5
not B=15 questions
