Question

Find the value of x in each figure :
2x + 30°
3x - 20°​

Answer 1

Answer:

2x+30°+3x-20°=180

5x=180-10

x=170/5

x=34

Answer 2

$\huge\color{green}{Answer:-}$

Find the value of x :-

$\mathtt{(a)-\:2x+30°}$

$\mathtt{2x+30°=180°}$

$\mathtt{2x=180°-30°}$

$\mathtt{2x=150°}$

$\mathtt{x=\frac{150}{2}}$

$\mathtt{x=75°}$

_______________________________

$\mathtt{(b)-\:3x-20°}$

$\mathtt{3x-20°=180°}$

$\mathtt{3x=180°-20°}$

$\mathtt{3x=160°}$

$\mathtt{x=\frac{160°}{3}}$

$\mathtt{x=53.33°}$
