Question

find x in the question​

Answer 1

Step-by-step explanation:

the sum of angles of a triangle is 180°

i.e 2x + 7 + 3x + 5 + 4x - 3 = 180°

i.e 9 x + 9 = 180°

i.e 9x = 171

x = 171 / 9

= 19

i.e the three angles are :

2x + 7 = 45°

3x + 5 = 62°

4x - 3 = 73°

hope this helps you :)

Answer 2

Answer:

✮We know that:

The sum of the triangle is 180°

✮Solution:

(2x+7)+(3x+5)+(4x-3)=180°

$⇒2x + 3x + 4x + 7 + 5 - 3 = 180$

$⇒9x + 9 = 180$

$⇒9x = 180 - 9$

$⇒x = \frac{171}{9}$

$⇒x = 19$

Therefore, The value of x is 19.
