Question

in the given figure find x​

Answer 1

⭐$\huge\pink{Given:}$

In ∆ABC,

• <A=(x+10) °

• <B=(3x+5) °

• <C=(2x+15) °

⭐$\huge\red{To Find: }$

• The value of x=?

⭐$\huge\blue{Solution: }$

Since,

We know that,

$um of all angles of a triangle is 180°.

: . <A+<B+<C=180°

→ (x+10) °+(3x+5) °+(2x+15) °=180°

→ 6x+30=180°

→ 6x=150°

→ x= 25°

: . The value of x is 25 °.

Answer 2

Answer :

$\sf\pink{Given}$

• Angle A is ( x + 10 )

• Angle B is ( 3x + 5 )

• Angle C is ( 2x + 15 )

$\sf\pink{To\: Find}$

• Value of "x" is ?

Explanation :

Rule :

Sum of all angles of a triangle is 180°

Therefore ,

$\longrightarrow\bf{x + 10 + 3x + 5 + 2x + 15 = 180 }$

$\longrightarrow\bf{x + 3x + 2x + 15 + 5 + 10 = 180 }$

$\longrightarrow\bf{4x + 2x + 20 + 10 = 180 }$

$\longrightarrow\bf{6x + 30 = 180 }$

$\longrightarrow\bf{6x = 180 - 30 }$

$\longrightarrow\bf{6x = 150 }$

$\longrightarrow\bf{x = \dfrac{150}{6}}$

$\longrightarrow\bf\pink{x = 25}$

• Therefore value of x is 25 .
