Question

find the value of the angles in given figure​

Answer 1

Answer:

The value of x is 42

Step-by-step explanation:

3x + 5 + 2x -25 = 180°

5x -20  = 180°

5x  = 180° + 20

5x = 210

x  = 210/5

x = 42

Answer 2

Answer:

3x+5=125°

2x-25= 55°

Step-by-step explanation:

3x + 5+2x-25=180°[ sum of liner pair of angle is 180° ]

5x-20=180°

5x=180°+20

5x=200

x=200/5

x=40

Now, put x= 40 in 3x+5 & 2x-25

3×40+5=125°

2×40-25=55°
