Question

question triangle as exterior angle is equal to 280 degree ratio between it interior opposite angle 2:3: find the measurement of 3 triangle??


answer let the interior angles be x and 3x
we know that exterior angle of triangle is equal to sum of interior opposite angles..


x+3x = 80°
4x=80°
x=80/4
x= 20°

so the angles are
x=20°

3x= 3×20°= 60°



so answer is 20°,60°....​

Answer 1

Step-by-step explanation:

As we know the sum of two interior opposite angles is equal to exterior angle.

Let the angles be x and 4x.

so,

x+4x=125

5x=125

x=125/5

x=25

Therefore,

1st angle is x=25 degrees

2nd angle is 4x=4∗25=100 degrees.
