The graph is the intersection of the interior of a circle with a half-plane.
Answer:
Θ = 50°
Step-by-step explanation:
Using the cofunction identity
cosx = sin(90 - x)
Given
cos40° = sin(90 - 40)° = sin50° ⇒ Θ = 50°
82.693
the rule is when its 4 and under round down and 5 and up round up
He has 15 quarters because
3.75 ÷ 0.25 = 15 = 15 quarters
10 × 10 = 50 dimes = 5
