Aseem and Stana are building model cars. Stana's car is 5 less than 2 times the length of Aseem's car. The sum of the lengths of
both cars is 20 inches. Write an equation to determine the lengths of Aseem's and Stana's cars. 2x − 5 + x = 20
5 − 2x + x = 20
2x − 5 = 20
5 − 2x = 20
Since it forms a "right triangle" we can apply trigonometry. sin x = oppo/hyp sin x = 13/20 x = sin^-1(13/20) x = sin^-1(0.65) x = 40.5 rounded to nearest degree x = 41 degrees
