Question

in the figure given at right the value of x​

Answer 1

Answer:

x = 35°

Step-by-step explanation:

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

5x + 5° = 180°

5x = 175°

x = 35°

Answer 2

We can recall now that the total sum of angle in a straight line is alwyas equal to $180^o$.

Given:

The angles in the straight line AC are $2x-10, 3x+15$

$2x-10+3x+15=180^o$

$5x+5=180^o$

$5x=180^o-5 =175^o$

$x=\frac{175}{5} = 35^o$

$x = 35^o$

The value of $x = 35^o$.
