Find the mesaure of <m and <n
there is two blue dots M and N pls tell me what they are

Answer:
<m=76°
<n=76°
Step-by-step explanation:
it's a isosceles triangle
according to the question the equation is
28+2x=180
2x=180-28
2x=152
x=152/2
x=76
Isosceles triangle has two equal sides so
<m=<n
therefore
<m=76°
<n=76°
