In a triangle the measure of the first angle is 24 degrees more than the second angle. the measure of the third angle is four ti
Leona [35]

The greatest angle in the given triangle is 104 degrees.

<h3>What is a triangle?</h3>
  • The polygon with 3 sides, three vertices, and three angles is known as a triangle.
  • A triangle's overall number of degrees is always 180 degrees.

Given:

  • Let, the second angle has a measurement of x degrees.
  • The first angle's measurement is 24 degrees greater than the second angle's measurement.
  • As a result, the first angle is (24+x) degrees.
  • The third angle is four times as large as the second.
  • As a result, the third angle has a measure of 4x.

So,

  • (24 + x) + x + 4x = 180
  • 6x = 124 - 48
  • 6x = 156
  • x = 156/6
  • x = 26

As a result, the second angle has a measurement of 26 degrees.

The first angle's measurement is now 24 degrees greater than the second angle's measurement.

Now,

  • = 24 + 26
  • = 50

As a result, the first angle has a measure of 50 degrees.

The third angle is now four times the size of the second angle.

So,

  • 4 × 26 = 104

Therefore, the greatest angle in the given triangle is 104 degrees.
