I think 10,000 not sure though
If solving for y:
→ 2x + y = 8
→ Take away 2x from both sides
→ y = 8 - 2x
If solving for x:
→ 2x + y = 8
→ Take away y from both sides
→ 2x = 8 - y
→ Divide both sides by 2
→ x =
Answer:
x = 30.
Step-by-step explanation:
Use the identity sin A = cos (90 - A).
So sin 30 = cos (90 - 30) = cos 60.
cos 2x = cos 60
so x = 30.
