Question

13. In a triangle, two angles are equal and each measures twice the third angle. Find the measures of all the angel​

Answer 1

Answer:

angle 1 and 2 measure 72 each and the third one measures 36

Step-by-step explanation:

let,

angle 1= 2x

angle 2=2x

angle 3=x

angle(1+2+3)=180

i.e 2x+2x+x=180

5x=180

x=36

hence,angle 1 and 2 = 2x =72 each
