Answer 1

Answer:

oues no. 3  solution

            given angle 1 =85

1. so,  anlge 1= angle3  [verticle oppsite angles]           5. angle 5 = angle7

                      85=85  

then , angle 1 +angle4= 180[sum of linear pair of angle ]

           85 +angle 4=180

            angle 4= 180 - 85

                         = 95

       2. so angle 4 = anlge 2 [verticle oppsotie angle ]

             angle 3= anlge 5[alternate opposite angle ]

                  85=85

        3. angle 2= angle 8[alternate opposite angle ]  

         4. angle 8= angle6 [alternate opposite angle ]  

Answer 2

Step-by-step explanation:

4.a) -3(x-1)+6 = 12

-3x+3+6 = 12

-3x+9 = 12

-3x = 12-9

-3x = 3

x = 3/-3

x = -1

b) 5t+17/3 = 9

5t+17 = 9×3

5t+17 = 27

5t = 27-17

5t = 10

t = 10/5

t = 2

3. Angle1 = 85°(given)

Angle3 = 85°(vertically opposite angle to angle1 are

equal)

Angle5 = 85°(interior angle to angle3 are equal)

Angle7 = 85°(vertically opposite angle to angle5 are

equal)

Angle4 = 180°-85°(supplementary angle)

= 95°

Angle2 = 95°(vertically opposite angle to angle4 are

equal)

Angle8 = 95°(interior angle to angle2 are equal)

Angle6 = 95°(vertically opposite angle to angle8 are

equal)
