you have two complementary angles. if the measure of the larger angle is 15 degrees more than 2 times the measure of the smaller angle, find the measures of the 2 angles.

    The key is to express both angles in terms of only a single variable. Also key is knowing the definition of complementary angles.

    i got x + y=90 and 2x +15 +y=90

    You're right that x + y = 90. Now, replace one of those variables so you only have one variable to deal with. You can solve from there.

    so u mean it would be 2x + 15 +x=90
