AB is tangent to the circle at B. M∠A=40 and mBC=130. a. Find x b. Find y
1 answer:
The values for x and y are respectively given as
- x = 50
- y= 90
This is further explained below.
<h3>What is the values for x and y ?</h3>Generally, the equation for secent is mathematically given as
Therefore
80 = 130-x
x = 50
b) To Solve for y Now we find a measure of arc CD
ArcCD = 360-130-50
ArcCD = 180
In conclusion,(1/2) of the arc measure is equal to the angle that is on and inside a circle.
y = 180/2
y= 90
