Question

FIND x IN THIS QUESTION​

Answer 1

Answer:

x = 42

Step-by-step explanation:

Here, we can see that the angles given are supplementary angles or else you can say they are in linear pair.........

So by that rule,

3x - 10 + 2x - 20 = 180

5x - 30 = 180

5x = 180 + 30

5x = 210

x = 210 / 5

x = 42

and if you need angles simply do,

(i) 3x - 10 = 3(42) - 10

               = 126 - 10

               = 116

(ii) 2x - 20 = 2(42) - 20

                 = 84 - 20

                 = 64
