The standard form is:
a x + b y = c
y = - 2/5 x - 3 / *5 ( we will multiply both sides of an equation by 5 )
5 y = - 2 x - 15
Answer:
2 y + 5 y = - 15
Draw a line from Y through the center of the circle to the opposite edge. Label the opposite edge T. ZYT = 90o. That's a property of a tangent line and a diameter touching the tangent point.
ZYX = 60o Given
TYX + ZYX = 90o Property of a diameter and circles. That's
TYX = 90 - 60
TYX = 30.
The arc measurement between T and X = 60o Property of a central angle and an angle whose vertex is on the circumference sharing the same endpoints of chord are related by a ratio of 2:1.
The rest of the arc = 120o. The rest of the arc is 180 - 60 = 120. The rest of the arc is XYZ which is 120o
Arc XYZ is bisected by YW. Therefore Arc XW = 120/2 = 60
The answer is A.
Answer:
About 660.5
Step-by-step explanation:
where r is the radius
and you get about 660.5 or an exact answer of (841/4)
