Answer:
missing angle <60 and side lengths 5, 5
Step-by-step explanation:
we understand from the given information that the triangle in question is a special right triangle
and since this is a special triangle the side lengths follows :
the side length that sees <90 is represented by 2x
the side length that sees <60 is represented by x
and the side length that sees <30 is represented by x
2x = 10 so x = 5 and x
= 5
