Abasketball player shoots the ball with an initial velocity of 17.1 ft/sec. at an angle of 45.6° with the horizontal. to the nearest tenth, find the initial horizontal component of the vector that represents the velocity of the ball. a. 5.1 ft/sec. b. 12.0 ft/sec. c. 12.2 ft/sec. d. 17.5 ft/sec.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

me! what did you put for this question?
