Question

one angle of a triangle is equal to the sum of the other two angles of that triangle the two smaller angles are in the ratio 2:8 what are the angles of the triangle ​

Answer 1

Answer:

90,72,18

Step-by-step explanation:

let two angles be 2x and 8x

third angle = ( 2x + 8x)

angle sum property of triangle is 180

Equation :

=> 2x + 8x + (2x+8x) = 180

=> 10x + 10x = 180

=> 20x = 180

=> x = 180/20

=> x = 9

Biggest angle => (2× 9)+(8×9) = 90

smaller angle => 2×9 = 18

smaller angle => 8× 9 = 72
