Suppose a certain baseball diamond is a square 80 feet on a side. The pitching rubber is located 54.5 feet from home plate on a line joining home plate and second base. (a) How far is the pitching rubber from first base?
(b) How far is it from the pitching rubber to second base?
(c) If a pitcher faces home plate, through what angle does he need to turn to face first base?

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

answer is because 4×10=40

and 98×4= is 392

40,392

i believe it's a.

i'm not sure on this one, most likely correct.
