Question

Please help i need answer and explanation.

Answer 1

Answer:

m<TVZ = 95

Step-by-step explanation:

2x+15+2x+5= 180

4x+20 =180

     -20  -20

4x=160

x= 40

2x+15= m<TVZ

2(40)+15 = m<TVZ

80+15 = m<TVZ

95 = m<TVZ

To check:

2x+5= <WVZ

2(40)+5 = <WVZ

80+5 = <WZV

85+95 = 180

The two angles together should equal 180. Comment if you have any questions :)

Answer 2

Answer:

95 degree

Step-by-step explanation:

Step 1 )  2x+15 vertical opp angle with missing angle and 2x +5 an be added to one another, when  - 180 degree = 0   as we need to divide total for x into 180 to find the value

Step 2)

2x+15 + 2x+ 5 - 180 = 0  

4x+ 20 -180 = 0  

4x-160 = 0

4x=160

x =160/4

x =40 degree    

Step 3) Find the degree value of 2x+ 15 = 2(40) + 15 = 80+15 = 95  

Step 4) You an also prove 180 degree total of 2x+ 5 = 2(40) + 5 = 80+5 = 85 where 95+85= 180
