Answer:

137°

Step-by-step explanation:

So the question given that triangle ABC is similar to triangle DEF right?

For similar triangles we get the following properties:

-corresponding angles are the same

[∴angle A = angle D, angle B = angle E, angle C = angle F]

-ratio of the corresponding sides of the two triangles are the same(not related to this question)

So, we get angle D = 64°, angle G = 64 + 73 = 137° (ext. ∠ of Δ)
