Determine r = distance from the origin to P. Finally, write down the value of the six trigonometric functions of θ.

I need help with this trig. math problem

Change 675° to racism measure in terms of pi

1. r=6cm, central angle=1.6 rad 2. r=14cm, central angle=0.25 rad 3. r=25 cm, central angle=1.75 rad 4. r=12cm, central angle= 3/4 rad THANK YOUU IN ADVANCE!💖

I just need help with this question please

My book has quite a few examples so I’ll just pick three. The directions are: find the exact value of theta in degree measure (0<theta<90°) and in radian measure (0<theta<90°),...
