# AC←→ is tangent to the circle with center at B. The measure of ∠ACB is 24°. What is the measure of ∠ABC?

Now we know that

Our goal is to find the third angle, so we use the property:

#color(brown)("Sum of the three angles of a triangle is"# #color(brown)(180^circ#

So,

Hpe this helps..... :)

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- A triangle has vertices A, B, and C. Vertex A has an angle of #pi/12 #, vertex B has an angle of #(5pi)/8 #, and the triangle's area is #15 #. What is the area of the triangle's incircle?
- How do you write the equation of the circle with endpoints of its diameter at (-4,7) and (8,-9)?
- Points #(2 ,1 )# and #(5 ,9 )# are #(3 pi)/4 # radians apart on a circle. What is the shortest arc length between the points?
