The largest angle of a triangle is 5 times as large as the smallest angle. The third angle is 12 degrees more than the smallest angle. Find the measure of all three angles.

Respuesta :

Answer:

the angle in ascending order is 24°, 36° and 120°

Step-by-step explanation:

The largest angle of a triangle is 5 times as large as the smallest angle

The third angle is 12 degrees more than the smallest angle.

let the smallest angle be x

the largest angle is 5x

the third angle is (12+x)

the sum of angles in a triangle is 180°

x + 5x + (12+x) = 180

x+5x+ 12+x = 180

7x+12 = 180

7x = 180 -12= 168

x = 168/7 = 24°

the smallest angle is 24°

the largest angle is 5x= 5 x 24 = 120°

the third angle is 12 +x = 12+24 = 36°

The measure of the three angles are 24, 36 and 120 degrees.

What are the measures of the angles?

A triangle is a polygon with three side. All angles measure up to 180 degrees.

Let:

  • x = smallest angle
  • 5x = largest angle
  • x + 12  = third angle

x + 5x + x + 12 = 180

7x + 12 = 180

7x = 180 - 12

7x = 168

x = 24

Largest angle = 24 x 5 = 120

Third angle = 24 + 12 = 36
