X+20=180 Find the value of x?

1 answer:

6 0

x = 160

Steps:
x+20=180
Subtract 20 from both sides
x+20-20=180-20
20 is crossed out
180-20 = 160
x = 160

To check plug in 160 for x
160 + 20 = 180
180 = 180

Hope this helps you! (:

If cos 60° = 1/2 and sin 60º = root 3/2 find cos 240° and sin 240".

Vesnalui [34]

Answer:

cos 240 deg = -1/2 and sin 240 = - root(3)/2

Step-by-step explanation:

if cos 60° = 1/2 and sin 60º = root 3/2 find cos 240° and sin 240".

we know that cos 240 = cos (60 + 180) = - cos 60 = - 1/2

cosine is negative when the angle is in the 3rd quadrant

sin 240 = sin (60 + 180) = - root(3) /2

sine is also negative in the 3rd quadrant.
