<span>triangle abc is similar to triangle def
</span>
m<b = m<e = 25
so
m<d = m<a = 45

answer:

<span>measure of angle a= 45 degrees</span>

Answer:

m∠a= $45\°$

Step-by-step explanation:

we know that

If two triangles are similar

then

The ratio of their corresponding sides are equal and the corresponding angles are equal

so

In this problem

m∠a=m∠d= $45\°$

m∠b=m∠e= $25\°$

m∠c=m∠f= $180\°-70\°=110\°$ ----> sum of internal angles of triangle must be equal to $180\°$
