Answer:
1.D
2.A
3.B
4.[tex]49^{\circ}[/tex]
Step-by-step explanation:
1.We have to find he pair of linear angles
From given figure
[tex]\angle KRM+\angle MRH=180^{\circ}[/tex]
[tex]\angle KRT+\angle KRM=180^{\circ}[/tex]
[tex]\angle MRH+\angle HRT=180^{\circ}[/tex]
[tex]\angle KRT+\angle HRT=180^{\circ}[/tex]
[tex]\angle ERM+\angle MRC=180^{\circ}[/tex]
[tex]\angle ERT+\angle CRT=180^{\circ}[/tex]
[tex]\angle ERT+\angle ERM=180^{\circ}[/tex]
[tex]\angle CRH+\angle HRE=180^{\circ}[/tex]
[tex]\angle KRC+\angle CRH=180^{\circ}[/tex]
Hence, option D is true.
2.We have to find the angle BHR
[tex]\angle NHD+\angle SHD=90^{\circ}[/tex]
[tex]8x+9x+5=90[/tex]
[tex]17x=90-5[/tex]
[tex]17x=85[/tex]
[tex]x=\frac{85}{17}[/tex]
[tex]x=5[/tex]
substitute the value of x
Then [tex]\angle SHD=9\times5+5=50^{\circ}[/tex]
[tex]\angle SHD+\angle RHS+\angle BHR=180^{\circ}[/tex]
[tex]90+50m\angle BHR=180[/tex]
[tex]\angle BHR=180-140=40^{\circ}[/tex]
Hence, [tex]m\angle BRH=40^{\circ}[/tex]
Option A is true.
3.We have to find the value of x
[tex]6x-82=3x+23[/tex] (vertical angles are equal )
[tex]6x-3x=23+82[/tex]
[tex]3x=105[/tex]
[tex]x=\frac{105}{3}=35[/tex]
Hence, the value of x=35
Option B
4.We are given that an angle measure [tex]41^{\circ}[/tex]
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
