```7.7 SOLVING RIGHT TRIANGLES
TO SOLVE A RIGHT TRIANGLE MEANS TO FIND THE MEASURES OF ALL OF ITS SIDES AND ANGLES. YOU CAN SOLVE A RIGHT TRIANGLE IF YOU KNOW EITHER OF THE FOLLOWING:
1) TWO SIDES LENGTHS
2) ONE SIDE LENGTH AND THE MEASURE OF ONE ACUTE ANGLE

USE A CALCULATOR TO FIND THE MEASURE OF EACH ANGLE TO THE NEAREST TENTH OF A DEGREE.
1) SIN A = 7/12 2) COS A = 0.3867
3) TAN B = 12/18 3
