Question

In the given figure, find x.

Answer 1

Answer:

X = 1

Step-by-step explanation:

2x + 15 + 3x + 5 + X + 10 = 180° (angle sum property of a triangle)

6x + 30 = 180°

6x = 180/30

X = 6/6

X = 1

Answer 2

$\boxed{ \underline{ \underline{ \footnotesize \tt{Solution:- }}}} \: \blue✪$

$\: \: \: \: \: \: \: \: \: \: \: \: \:$

$\footnotesize\tt \blue{We \: know \: that \: Sum \: of \: all \: angles \: in \: triangle \: is \: 180°}$

$\: \: \: \: \: \: \: \: \: \: \: \: \:$

$\footnotesize\tt{(2x + 15)° + (x + 10)° + (3x + 5) °= 180°}$

$\footnotesize\tt{2x + x + 3x+ 15°+ 10° + 5°= 180°}$

$\footnotesize\tt{6x+ 30°= 180°}$

$\footnotesize\tt{6x= 180° - 30°}$

$\footnotesize\tt{6x= 150°}$

$\tt{x \: = \: } \footnotesize \tt{ \frac{150°}{6} }$

$\footnotesize\tt{x \: = \: } \tt{ \cancel \frac{ 150°}{6} }$

$\boxed{ \underline{ \underline{ \footnotesize \tt{ x = 25° }}}} \: \blue✪$
