Priya noticed in the last activity that between the 2 triangles, you only need to know 4 angles to show that they are similar. She wondered which fourth angle would work to prove that triangle RST is similar to triangle EFG.

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

96 39 cause 135 -96=39 im smart (i used a calculater)

139 divided by a number

step-by-step explanation:

any of them that add up to 180 degrees.
