Answer 1

Step-by-step explanation:

value of angle of triangle is 180'

Answer 2

Answer:

1. x=60
2. x=10
3. x=15
4. x=36

Step-by-step explanation:

in all angles if property will be used

1) x-5+x+x+5=180. (by angles sum property)

x+x+x=180

3x=180

x=180/3

x=60

2) 3x+9x+6x=180. (by angles sum property)

18x=180

x=180/18

x=10

3) x+7x+30+2x=180. (by angles sum property)

10x=180-30

x=150/30

x=15

4) x+2x+2x=180. (by angles sum property)

5x=189

x=180/5

x=36

ok
