Answer:
15° and 100°
Step-by-step explanation:



3 × 5 = 15, 20 × 5 = 100. So the other two angles measure 15° and 100°.
Answer:
50
Step-by-step explanation:
Let's drag the x line to the other side with the 14 and 48.
Then we do the Pythagorean theorem like 14^2 + 48^2 = x^2.
So then we get that x^2 is 2500
then we clearly know the square root of 2500 is 50
So 50 is our answer.
