Let the common multiple be x
Sum of angles of a triangle = 180°
one of the angles of triangle is right angle (90°)
(2x)°+(7x)°+90°=180°
9x=90
x=10
hope it helps

Answer:
let x=2a and y =7a
so as we know in a right angled triangle on angle is 90°.
hence the above is right angled triangle one angle is 90° and other two are 2a and 7a
In a triangle sum of all angle is 180°
so,
90° +2a+ 7a =180°
= 2a + 7a =180°-90°
= 9a = 90°
a = 90°÷9
= a = 10°
therefore x= 2×10°= 20°
y= 7×10°=70°
