Ac←→ is tangent to the circle with center at b.
the measure of ∠acb is 71°.

what is the measure of ∠abc?
enter your answer in the box.
m∠abc = __ °

The value of m∠ABC = 19 °

Step-by-step explanation:

Since we have given that

AC is tangent to the circle with center at B.

The measure of ∠ACB = 71°

And we know that "Radius is the shortest distance from the center to the tangent".

So, Radius is always perpendicular to the tangent.

So, the measure of ∠BAC = 90°

Consider, ΔABC, we get that

Hence, the value of m∠ABC = 19 °

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
