An isosceles triangle has base angles that each measure 52º. Which equation can be used to

Mathematics
1 answer:
VMariaS [17]3 years ago
5 0

Answer: I'm not the best at this but the answer that makes the most sense is B. 104+z=180

Step-by-step explanation: A triangle has 2 sides which are both 52 degrees. Add those to get 104 degrees. Now since a triangle has 3 sides we need to find the one other side so no answers with 2z match meaning the answer should be B.

f is differentiable across its domain, so the MVT says there is some value of c in the open interval (a,b) such that

f'(c)=\dfrac{f(b)-f(a)}{b-a}

You have

f(x)=Ax^2+Bx+C\implies f'(x)=2Ax+B

so the equation above becomes

2Ac+B=\dfrac{(Ab^2+Bb+C)-(Aa^2+Ba+C)}{b-a}

Solve for c.

2Ac+B=\dfrac{A(b^2-a^2)+B(b-a)}{b-a}
2Ac+B=A(b+a)+B
2Ac=A(b+a)
c=\dfrac{b+a}2

so c is indeed the average of the endpoints, i.e. the midpoint.
