Explanation:
1.We have to find he pair of linear angles
From given figure
![\angle KRM+\angle MRH=180^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/hswoc116t4f2xo3atx9e63w9h61ytz0snp.png)
![\angle KRT+\angle KRM=180^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/p9ahlm0wcf99dkb63wcsi9r0optych1fh9.png)
![\angle MRH+\angle HRT=180^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/m0r0im9unen2wqmohuts61x0bfyodc3oa4.png)
![\angle KRT+\angle HRT=180^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/74luz42jtf8d66q689a1om3pd7rvix3jhb.png)
![\angle ERM+\angle MRC=180^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/ap2unc265px66cw3kegodb7fdhvsrw182t.png)
![\angle ERT+\angle CRT=180^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/fn8qu0pgbypvyxzsa6v3dkmlcf48z0zbsz.png)
![\angle ERT+\angle ERM=180^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/tw5e8cs5ez0lbdwqp28b6q5fscg21wc88b.png)
![\angle CRH+\angle HRE=180^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/2w45vp6kiz2sgxhm04rbjpgvabmqsjbp6q.png)
![\angle KRC+\angle CRH=180^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/3h63tf05a9t80dixhxznp88x6ij4r30i18.png)
Hence, option D is true.
2.We have to find the angle BHR
![\angle NHD+\angle SHD=90^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/a281v0zfcvi77gk1xy4epxigiyhokfz44r.png)
![8x+9x+5=90](https://img.qammunity.org/2019/formulas/mathematics/middle-school/5liomk1588v2e6yr6f6ge08yx1je0wdtb9.png)
![17x=90-5](https://img.qammunity.org/2019/formulas/mathematics/middle-school/7xiee5ruilnwnmawqu88pyyv2ydh37fouk.png)
![17x=85](https://img.qammunity.org/2019/formulas/mathematics/middle-school/m7lt1rbp6sqdx0hhy1nlxd89xm784j3dnm.png)
![x=(85)/(17)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/a5bwwmyf1dgp8zhzcimrj3w7qmy4d0x4ss.png)
![x=5](https://img.qammunity.org/2019/formulas/mathematics/college/m3atvlkke09t7u8nz2kzldrh2p4btreb3b.png)
substitute the value of x
Then
![\angle SHD=9*5+5=50^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/72kbl7cg6ke3ovlyaqlzyk0igkfn8u85q8.png)
![90+50m\angle BHR=180](https://img.qammunity.org/2019/formulas/mathematics/middle-school/89wzu2ay9i0co9lwws5upi7fn1okydw7wh.png)
![\angle BHR=180-140=40^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/lj6gvubl0il81nn1zo4883mf2oewod3ydf.png)
Hence,
![m\angle BRH=40^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/u6ocp694g1f8zak0zbl87ka2stps3o06np.png)
Option A is true.
3.We have to find the value of x
(vertical angles are equal )
![6x-3x=23+82](https://img.qammunity.org/2019/formulas/mathematics/middle-school/5qejjuqftbw8ck9343p1hug0ey9b6dq2h4.png)
![3x=105](https://img.qammunity.org/2019/formulas/mathematics/college/f7tis8djims28ef84qyahnbcm33ipnp30g.png)
![x=(105)/(3)=35](https://img.qammunity.org/2019/formulas/mathematics/middle-school/5pieddob811bxbu7l1we4dwq9sq8je055p.png)
Hence, the value of x=35
Option B
4.We are given that an angle measure
![41^(\circ)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/qdbwu0seom49p271b14h8xx223215fpux3.png)
We have to find the value of its complement
We know that complete angles sum is equal to 90 degrees
Therefore, complement =90-41=[/tex]49^{\circ}[/tex]
Hence, the complement of 41 degrees is 49 degrees.
Option B
