OK. Even though you only gave me part of the paragraph, I read that much, and I think I'm ready to select the correct answer now. What are the choices ?
I would say choice A
but im not absolutely sure
The percent of change is 71%
Answer:
The answer is B. Acute isosceles
Every triangle has an angle measure of 180 degrees.
so 42+20+x (where x is the measure of the third angle)=180
Combine like terms.
62+x=180
Subtract 62 from both sides
x=118.
