Question

Find the value of X in the following figures.
$< x = 2x = 180.$
​

Answer 1

Answer:

sum of all angle =180 degree

in 1, st question answer 70+65+x=180

135+x=180

x=45

you can solve all question for this method

Answer 2

1.) x+70+65 = 180

x = 180 - 135

x = 45

2.)x+2x+90 = 180

3x+90 = 180

3x = 2

x = 2/3

3.) x+2x+3x = 180

6x = 180

x = 30

4.) x+x+80 = 180

2x = 100

x = 50

5.) x+x+x = 180

3x = 180

x = 60

6.) x+130+35 = 180

x = 180 - 165

x = 15
