Question

Find x?
solve it with process please​

Answer 1

Answer:

in this figure, the sum of COB and COA is 180 degree

so, according to the question

$3x + 20 + 2x - 10 = 180$

$5x + 10 = 180$

$5x = 180 - 10$

$5x = 170$

$x = \frac{170}{5}$

$x = 34$

hope it helps

Answer 2

Answer:

( 2x - 10 )= 58 degrees

( 3x + 20) = 122 degrees

Step-by-step explanation:

the horizontal straight line angle in a circle which cuts half will get 180 degrees

180 = ( 2x - 10 )+( 3x + 20)

180 = 5x + 10

x = 34 degrees

substitute x values in both the angles , we can get

58,122 = 180 degrees
