Using the rational root theorem, it is found that your friend is correct.
<h3>What is the rational root theorem?</h3>
- It is a theorem that states that for a polynomial with integer coefficients, with q being the factors of the leading coefficient and p being the factors of the constant, every <u>possible rational root</u> is the format  . .
In this problem:
- The leading coefficient is 1, hence it's only factor is  , thus guaranteeing that every possible rational zero is an integer, which means that your friend is correct. , thus guaranteeing that every possible rational zero is an integer, which means that your friend is correct.

m∠A = 40
Step-by-step explanation:
Given AB =AC and  m∠B = 70
Since AB =AC , Triangle ABC is an isosceles Triangle and the corresponding angles B and C are equal.
So m∠B = m∠C = 70
The sum of the 3 Angles of a triangle is 180°. 
=> m∠A  + m∠B + m∠C = 180
=> 140 + m∠C = 180
=> m∠C = 40
Hence the answer is  m∠C = 40
