The image of a parabolic lens is traced onto a graph. The function f(x) = (x + 8)(x – 4) represents the image. At which points does the image cross the x-axis? (–8, 0) and (4, 0)
(8, 0) and (–4, 0)
(2, 0) and (–1, 0)
(–2, 0) and (1, 0)

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.
