Answer:
x=17 is the final answer.
Explanation:
Given that m ∠TSR = 84
SQ is angle bisector of ∠TSR
m ∠RSQ = 3x-9
Now using those information, we need to find the value of x.
Since SQ is angle bisector of ∠TSR, then we can write:
∠TSR =2 (∠RSQ)

![(84)/(2)=(3x-9)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/vghk9x8m67jd13yzmo7e8qgvwkmavyioqd.png)

![51=3x](https://img.qammunity.org/2020/formulas/mathematics/middle-school/n6561wijgoqr1p0l43so3nkzmghf2t73np.png)
![(51)/(3)=x](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ujh2l7vhfagl5kxxzf6ktr19jir1s3t33a.png)
![17=x](https://img.qammunity.org/2020/formulas/mathematics/middle-school/859mcpkreyrmy362m7oq7ky29hd74ph6bx.png)
Hence x=17 is the final answer.
