Question

The sum of the measures of angle X and angle Y is 90. If the measure of angle X is less than twice the measure of angle Y, what is the measure of angle X

Answer 1

x+y=90
x<2y
x+y< 3y
but x+y=90
90<3y
⇒ y>30
for example y=31, then x= 59
y=32, x= 58
.............................................
y=40, x=50
