Question

3. In the given figure, find x.
​

Answer 1

Answer:

25°

Step-by-step explanation:

2x+15+x+10+3x+5=180 (AS THE SUM OF ALL ANGLES OF A TRIANGLE IS 180°)

6x+30=180

6x=150

x=25°

Answer 2

Answer:

✮We know that:

The sum of the triangle is 180°.

✮Solution:

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

$⇒2x + x + 3x + 15 + 10 + 5 = 180$

$⇒6x + 30 = 180$

$⇒6x =180 - 30$

$⇒x = \frac{150}{6}$

$⇒x = 25$

Therefore, The value of x is 25.
