Question

16. In a right-angled triangle, one of the two angles (other than right angle) is 4 times the other angle. Find the three
angles of the triangle ​

Answer 1

Answer:

72

Step-by-step explanation:

let one angle be x

and the other angle be 4x ( since it is 4 times the. other)

ATQ,

in right angle triangle one angle is 90 degrees

so, 90+x+4x=180 (angle sum property of triangle)

also 90+5x =180

and 5x= 180-90

=5x=90

= x =90/5

=x = 18

hence one angle is 90

another angle is x = 18

and other angle is 4x = 4*18 =72
