What is the measure of ZACB ?
Answer:
Your Answer Would be 90° Or 180° My friend!
A triangle's angles add up to 180 degrees because one exterior angle is equal to the sum of the other two angles in the triangle.
Hope this Helps!!!

Answer:
It is a Non-Linear graph:
Answer:
I’m pretty sure it’s Triangle ABC is congruent to Triangle DEF.
Step-by-step explanation:
If you rotate Triangle DEF to where the 90 degree angle is on the bottom right, you can the compare the two triangles. You can divide 300/25, 240/20, and 180/15. They all result in 12 meaning they are congruent and similar in that way. (I’m only 90% this is right btw)
If in a fraction, the numerator or the denominator or both are fractions, then it is called a complex fraction.
Example 1:

Here, since the numerator is a fraction, it is a complex fraction.
Example 2:

Here, since the numerator and the denominator are fractions, it is a complex fraction.
