Question

Find the value of x...in both cases..plz

Answer 1

hello users......

we have to find the value of x

solution:-
in first case
the sum of all the angles = 360°
=> 2x+2x+x+60° = 360°
=> 5x = 360-60 = 300°
=> x= 60°

in 2nd case
the sum of all the angles = 180°
=> 3x -5+x+20 +65° = 180°
=> 4x = 180°-80=100
=> x= 25°

⭐⭐ hope it helps ⭐⭐

Answer 2

I) 2x+60°=180°
X=120°/2
x=60°
II)3x-5+x+20+65=180°
4x+80°=180°
4x= 100°
x=100/4
x=25
