The lines in the figure are tangent to the circle at points a and b. find the measure of value of arcab for m

110

Step-by-step explanation:

There is a theorem that says "The measure of an angle formed by a secant and a tangent drawn from a point outside the circle is HALF the difference of the intercepted arcs "

Hence we can say:

We can say:

Also, we know that circle's degree measure is 360, thus we can say:

To find Arc AB, we can use the two equations and add, thus we get:

Thus, arc AB = 360 - 250 = 110

2nd answer choice is right.

its d. the first coordintaes are 10,32

step-by-step explanation:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
