Answer:
<h2>The interior angles of triangle EFG are 30°, 50° and 100°.</h2>
Step-by-step explanation:
We know by given that .
Similarities refers to proportional sides and congruent angles, so
, by corresponding elements.
Therefore,
By the same reason,
Then,
, by internal angles theorem.
Replacing values, we have
Therefore, the interior angles of triangle EFG are 30°, 50° and 100°.
