The graph of a curve that passes the vertical line test is known as a function. Functions are graphical representations that may have multiple x-values for a given y-coordinate, but will never have multiple y-values for any given x-coordinate.
Hope that helped! =)

WCD = (6-2)*180/6 = 120
BCD = (5-2)*180/6 = 108
360-120-108=132 (angle at a point)
CBW = (180-132)/2 = 24 (isosceles triangle)
Answer: The measure of ∠BEF=110°.
Step-by-step explanation:
Given: In cyclic quadrilateral ABCD, ∠C = 110°
Then, ∠A+∠C=180° [The sum of opposite angles in a cyclic quadrilateral is 180 degrees.]
⇒ ∠A+ 110°=180°
⇒ ∠A = 180° - 110°
⇒ ∠A = 70°
In cyclic quadrilateral ABEF,
∠A+∠E=180° [The sum of opposite angles in a cyclic quadrilateral is 180 degrees.]
⇒ 70° + ∠E=180°
⇒∠E=110°
Hence, the measure of ∠BEF=110°.
Answer:
Step-by-step explanation:
- x² + 20² = 25²
- x² + 400 = 625
- x² = 225
- x = √225
- x = 15
