Answer:
s=3
Explanation:
To solve this problem, you must assume that angle QPS is the same as angle QRS, which makes it both equal to 110°. The entire triangle should be equal to 180°, which means that 180 is equal to 2(11s+2). If you subtract 110 from 180, you get 70°=22s+4, which leads to 66=22s, and s is equal to 3.
