It’s 12 degrees because as a whole it is 180 degrees no matter what. 180-90 is 90, and 90-78 would be 12. Therefore the answer would be 12

Answer:

PRS = 12

Explanation:

The three angles form a straight line so their measures add to 180

PRS +90+78 = 180

Combine like terms

PRS + 168 = 180

Subtract 168 from each side

PRS+168-168 =180-168

12 = PRS
