Find the exact value of tan 2x if sin x = -4/5. (Quadrant III)

sin x = -0.8

x = -53.13010235 (used inverse of sin)

tan 2x

tan -106.2602047

= 0.61854704132

1. minimum

2. 6400

3. eight

hope this !

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
