Answer:
Step-by-step explanation:
so all the angles of a triangle add up to 180 degrees
180-42-62= 76
so we know angle TUS is 76 degrees
the other triangle has an angle of 78 degrees which isn't 42, 62, or 76.
The triangles are not similar because similar shapes have congruent angles
So the proportion would go as follows
5.5. 7.5
=
4.5. 60
To solve this you just cross muliply and divide.
I hope this helps you
