Question

if one angle ofa triangle is equal to the sum of other angle show that the triangle is right angle triangle​

Answer 1

Step-by-step explanation:

let the bigger angle be 'x'and smaller one be 'y'and'z'.

we know that in a triangle all the sums 180

x+(y+z)=180

but x=y+z

x+x=180

2x=180

x=90
