Question

The angles of a triangle are in the ratio 3:7:8. Find the greatest and the smallest angles. The sum of angles of a triangle is 180degree​

Answer 1

Step by step explanation

Let the angles be

1st angle=3×

2nd angle =7x

3rd angle=8x

Sum of the angles of triangle =180 degrees

So angle 1 +angle 2+angle 3=3x+7x+8x=18×

So 18x=180 degrees

×=180/18=10

×=10

Now 1st angle=3x=3×10=30 degrees

2nd angle=7x=7×10=70 degrees

3rd angle =8x = 8×10=180 degrees

So smallest angle is 30 degrees

Largest angle is 80 degrees

Answer 2

Answer:

Let the angles be

1st angle=3×

2nd angle =7x

3rd angle=8x

Sum of the angles of triangle =180 degrees

So angle 1 +angle 2+angle 3=3x+7x+8x=18×

So 18x=180 degrees

×=180/18=10

×=10

Now 1st angle=3x=3×10=30 degrees

2nd angle=7x=7×10=70 degrees

3rd angle =8x = 8×10=180 degrees

So smallest angle is 30 degrees

Largest angle is 80 degrees
