Question

The angle of a triangle are x,x+15and 2x-15.find the smallest angle of a triangle

Answer 1

Answer:

smallest angle is 60

Step-by-step explanation:

x+X+15+2x-15=180

3x=180

X=60

Answer 2

given :-

angles of a triangle are x, x + 15 and 2x - 15

here, we've to find the smallest angle of the triangle.

so first of all, we needa know the value of x.

we know that, sum of all angles in a triangle = 180°

so we can write,

➡ x + x + 15 + 2x - 15 = 180°

➡ 4x = 180°

➡ x = 180/4

➡ x = 45°

the angles are :-

• x = 45°

• x + 15 = 60°

• 2x - 15 = 75°

hence, the smallest angle of the triangle is x = 75°
