I gotten this question before the answer is 3
I think it’s A I could be wrong tho
It
is given that ∠B ≅ ∠C. Assume AB and AC are not congruent. If AB >
AC, then m∠C > m∠B by <span><span>the triangle parts relationship theorem</span>. If AC > AB, then m∠B > m∠C for
the same reason.
However, using the given statement and the definition
of congruency, we know that m∠B = m∠C.
Therefore, AB = AC and AB ≅ AC.</span>
The answer is h = 3 - .6 = 2.4
