Question

find the value of x if the three angles of a triangle are 3x , x by 2 and 5x by 2 . solve please​

Answer 1

Answer:

3x + x/2 + 5x/2 = 180°

3x + x/2 + 5x/2 = 180°=> x = 30°

1. 3x + x/2 + 5x/2 = 180°=> x = 30°by solving equation u get x as 30°
2. 3x + x/2 + 5x/2 = 180°=> x = 30°by solving equation u get x as 30°I put sum of given angle is 180° as sum of all angles in a triangle is same

Answer 2

Answer:

x=30°

1st angle =3x=3×30°=90°

2nd angle =x/2=30°

/2=15°

3rd angle =5x/2=5×30/2=150/2=75

Step-by-step explanation:

Sum of all angle of triangle =180°

3x+x/2+5x/2=180°

6x+x+5x/2=180°

12x/2=180°

12x=180°×2

12x=360°

x=360°/12

x=30°
