Answer:
can you add a picture because i don't know what your talking about
Step-by-step explanation:
Keeping in mind the formula for circumference is Pi x Diameter, you simply multiply 45 by pi.
This gives you 141.3716694
Only two triangles:
The 90* angle is stable, so you can change only the position of the 50* and 40* angles.
