Answer:
<B=55°, <D=55°
Step-by-step explanation:
in a parallelogram, opposite angles are congruent. so:
3n-5=2n+15
n-5=15
n=20
now that we know n is 20, we can substitute that into either <B or <D to figure out what their measures are (since they are congruent, they'll both have the same angle measure)
m<D=3n-5
m<D=3(20)-5
m<D=60-5
m<D=55
therefore, both <B and <D equal 55°.
