Answer:
(7 x 2 + 4x- 26)-(-7 x 2 - 3x + 15)
(7 x 2 + 4x -26) (7 x -2 + 3x - 15)
(14 + 4x -26) (-14 + 3x - 15)
(4x - 12) (3x - 29)
Since this is a right triangle, a triangle with a 90 degree-angle, we can use the trigonometric functions. An example would be the sine function. With respect to the angle, it has the opposite side (o), the adjacent side (a), and the longest side called hypotenuse (h). For the sine function, it would be sine theta = opposite/hypotenuse. Using this relationship,
sin 38 = BC/5
BC = 5*sin38
BC = 3.08 units
