Question

find the value of x in the figure​

Answer 1

Answer:

x = 35°

Step-by-step explanation:

Given,

∠AOC + ∠BOC = 180°   [Since linear pairs]

Solution:

=> 2x - 10 + 3x + 15 = 180

=> 2x + 3x + 15 - 10 = 180

=> 5x + 5 = 180

=> 5x = 180 - 5

=> 5x = 175

=> x = $\frac{175}{5}$

=> x = 35

Result:

Hence, required value of x is 35° (Ans)

Answer 2

Answer:

2x -10 +3x +15 = 180 ( linear pair)

2x +3x -10 +15 = 180

5x+5 =180

5x = 180-5

5x = 175

x = 175/5

x = 35 •
