Question

in the given figure, find x

Answer 1

Answer:

angle A + angle B + angle C = 180°

x+10+3x+5+2x+15=180

x=25°

Answer 2

$\huge→\underline\mathbb\red{AnsWer}{⚡}$

$Angle\: sum \: property\: of \: a\:∆=180°$

$(2x + 15)° + (x + 10)°+ (3x + 5)° = 180° \\( 6x + 30)° = 180° \\ 6x = 180° - 30° \\ 6x = 150° \\ x = \frac{150°}{6} \\ x = 25$

Hence, the value of x is 25°
