Everything = 180 degrees
2X = 180 - 40 - 40 -30
2x = 70
X= 35
The area of a circle, given the circumference, is found using this formula:
A = C²/4π
Therefore,
A ≈ 451.93 cm²
Answer:
4.65
Step-by-step explanation:
Answer:
Step-by-step explanation:
<u>Use cosine:</u>
- cos = adjacent / hypotenuse
- cos ∠L = KL/JL
- cos 21° = 4/x
- x = 4 / cos 21°
- x = 4.3 (rounded)
Answer:
The correct option is D.Any real number value of x satisfies the equation.
