Find m∠ J

Use a calculator. Enter only a number

26 degrees.

Step-by-step explanation:

We are given

We are trying to find angle measure of j.

Since we are given a side opposite of our angle we are trying to find and a side adjacent to the angle we are trying to find we are going to use tan ratio.

since we are trying to find the angle measure apply inverse trig function

Plug 46 for opp and 93 for adj.

which is about 26 degrees.

the answer is 48m^2!

step-by-step explanation:

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).
