Answer:
49 Degrees
Step-by-step explanation:
The teacher must have forgotten to add the degrees symbol on the number 13 so it must have confused you.
Step 1:
Add 13 and 28 together.
Step 2:
Since it is a Right-Angled triangle, we do 90-(13+28)
Step 3:
We get an answer of 49 Degrees.
Hope that makes sense!
