Euclid (circa330BC) would have been shocked to learn that it is possible to find the sine of a 480degree angle as right triangle trigonometry gives no values for angles larger than 90 dergrees

The measure of the angles of triangle abc are given by the expressions in the table. angle-measure a-48 degrees b-(6x-28)degrees c- (2x) degrees find the value of x. then find the measures of angles b and c. enter your answers in the boxes. x= m m
