Question

Find the value of x ​

Answer 1

Answer:

2(x-36)=2x-72+x=180

3x-72=180

3x=180+72

3x=252

x=252/3

x=84cm/m(what the measure is)...

Answer 2

Given :

$\angle \: AOB \: = 2(x-36)° \\ \angle \: AOC \: =x°$

To find :

$•Value \: of \: x$

Solution :

$\therefore2(x - 36) \degree + x \degree \: = 180 \degree \\ -( Angles \: in \: linear \: pair) \\ \\ \therefore2 \times x - 2 \times 36 + x = 180 \degree \\ \\ \therefore2x - 72 \degree + x = 180 \degree \\ \\ \therefore \: 3x - 72 \degree = 180 \degree \\ \\ \therefore \: 3x = 180 \degree + 72 \degree \\ \\ \therefore \: 3x = 252 \degree \\ \\ \therefore \: x = \frac{252}{3} \\ \\ \therefore \: \boxed {x \: = 84 \degree}$

Let us find the measures of angles :

$1) \angle AOB = 2(x-36)° \\ = 2 \: (84 - 36) \degree \\ = 2 \: (48) \degree \\ = 96 \degree$

$2) \angle AOC = x \degree \: \\ = 84 \degree$
