If r=20.5 and s=34.2 find s round to the nearest tenth

option d

Step-by-step explanation:

Remember the identity:

The inverse of the tangent function is arctangent. You need to use this to calculate the angle "S":

Knowing that: you need to find the measure of the angle "S" , (which is the adjacent side) and (which is the opposite side), you can sustitute values into

Then, you get that the measure of "S" rounded to the nearest tenth is:

1010: 3030

is it i think
