Two complementary angles have a ratio of 11 to 4. What are the measures of the angle?

OpenStudy (sloppycanada):

Do you know what a complementary angle is?

OpenStudy (briellshaw):

nope. I forgot

OpenStudy (sloppycanada):

A complementary angle is where when two angles are added together, they are equal to 90 degrees. Angle A + Angle B = 90 degrees.

thx

Directrix (directrix):

11x + 4x = 90 15x = 90 x = ? @BriellShaw

OpenStudy (briellshaw):

6

Directrix (directrix):

One angle has measure 6 times 11 = ? The other has measure 6 times 4 = ?

Directrix (directrix):

When you get those two answers, add them to see if they sum to 90. They should if they are complementary angles.
