Question

(1)
angles.
If the two acute angles of a right angled triangle are in the ratio 7: 8, find these angles​

Answer 1

Step-by-step explanation:

in right triangle one angle is 90⁰

let common ratio be x

therefore one angle = 7x and other = 8x

in triangle sum of all three angles is 180⁰

angle 1 + angle 2 + angle 3 = 180⁰

7x + 90 + 8x = 180⁰

15x = 90

x = 6

therefore angle 1 = 7x = 7*6 = 42⁰

angle 2 = 8x = 8*6 = 48⁰

hope it is helpful!

Answer 2

Step-by-step explanation:

in right angle one angel is 90°.

let common ratio be x.

therefore one angel =7x and other =8x

in triangle all three angel is 180°

angel 1 + angel 2 + angel 3 = 180°

7x + 90 + 8x = 180°

15x + 90

x=6

therefore angel 1 = 7x = 7*6 = 42°

angel 2 = 8x = 8*6 = 48°
