Answer:
Θ = 50°
Step-by-step explanation:
Using the cofunction identity
cosx = sin(90 - x)
Given
cos40° = sin(90 - 40)° = sin50° ⇒ Θ = 50°
56
Step-by-step explanation:
The whole angle is 132 and half of it is 76, so the other portion would be 56 i believe.
Answer:
Step-by-step explanation:
Remark
If the horizontal lines are parallel, then 2x + 20 = 3x - 10
Equation
2x + 20 = 3x - 10
Add 10 to both sides
2x + 20 + 10 = 3x
Subtract 2x from both sides
30 = x
2x + 20 = 2*30 + 20 = 80
The green table looks correct, I think that one's B.
