16. If triangle ABC is isosceles, and if AB = BC and

Answer:
C. 39
Step-by-step explanation:
If AB = BC, and angle A is 39 degrees. we can assume that angle C would have a similar angle.
Since in △ABC , AB=BC
∴ the triangle is isoceles.
In an isoceles triangle the angles opposite to equal sides are equal.
∴∠A=∠C
This means that C.39 is the correct answer
Answer:
39, C
Step-by-step explanation:
If angle A = 39, then the angle C is equal to A. This may seem like a weird question, but it’s the way that the triangle is positioned.
Also, you can prove this by looking at the equation provided in the prompt.
B is the vertex that they are creating this problem from, therefore, it may be helpful to turn the triangle around!
