The measure of the third angle in an isosceles triangle is 61.5 more than the measure of either of the two equal angles. Find the measure of the third angle.

Respuesta :

Answer:

Let's consider

 

equal angles in isosceles triangle = x

 

third angle = x+61.5

 

Addition of internal angle of Triangle = 180

 

2 equal angle + third angle = 180

 

x + x +x+61.5 =180

 

3x +61.5 =180

 

 

3x = 118.5

 

x = 39.5

 

so measure of equal angles = 39.5

 

and third angle = x+ 61.5 = 39.5 +61.5 =101

Step-by-step explanation:

Answer:

101°

Step-by-step explanation:

let the angles be x,x,x+61.5

then x+x+x+61.5=180

3x=180-61.5=118.5

x=118.5/3=39.5

so third angle=39.5+61.5=101°
