Question

in a right angled triangle one of the two angles (other than right angle) is 4 times the other angel . find the three angles of the triangle​

Answer 1

Answer:

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

Answer 2

Answer:

let angles be x and 4x then

sum of all the angles is 180

90 +x+4x=180

5x=180-90

x= 90÷5

x=18

1st angle=18

2nd angle=4×18

=72

1st angle=18

2nd angle=72

third (right)angle=90
