Question

angles of a triangle are 3x didi 2 x minus 7 degree 4 x minus 11 degree find the value of x​

Answer 1

Correct Question:

• Angles of a triangle are 3x, (2x-7) and (4x-11) degrees . Find the value of x.

Answer:

$\large\boxed{\sf{x=22}}$

Step-by-step explanation:

Given angles of ∆

• 3x
• 2x - 7
• 4x - 11

We know that sum of angles of a ∆ is 180°

$= > 3x + 2x - 7 + 4x - 11 = 180 \\ \\ = > 9x - 18 = 180 \\ \\ = > 9x = 180 + 18 \\ \\ = > 9x = 198 \\ \\ = > x = \frac{198}{9} \\ \\ = > x = 22$

Hence, x = 22

Given,

TheAngles are:

☆ 3x

☆2x-7

☆4x-11

$sum \: of \: all \: angles \: in \: a \: triangle \: = 180 \\ thus \\ 3x + (2x - 7) + (4x - 11) = 180 \\ 9x - 18 = 180 \\ 9x = 180 + 18\\ 9x = 198 \\ x = 198 \div 2 \\ x = 22(ans)$
