Question

The measure of ac = 7, mbac = 80°, mabc = 50°, the measure of nm = 7, mlnm = 80°, and mnlm = 50°. do the measurements indicate that abc nlm?

Answer 1

*I need more detail* but if I guessed than the question is asking if the are equal triangles.

Δabc=Δnlm

Explanation:

Draw out both triangles and label them as described in the question. If one angle of the triangles are 80° and 50° than the other angle has to be measured as 50° because all the angles have to add up to 180°. And both triangles are said to have angles 80° and 50°. The length of ac and ab are equivalent because it is an isosceles triangle and same goes for Δnlm.
