Question

One angle of a triangle is 90 other
two angles are in the ratio 7:3. find them
​

Answer 1

Answer:

63:27

Step-by-step explanation:

90+7x+3x=180

90+10x=180

10x=90

x=10

Answer 2

Answer :

angle 1 =63°

angle 2 =27°

Step-by-step explanation:

Let the 1st angle be 7x

2nd angle =3x

(given)3rd angle =90°

NOW,

angle 1 +angle 2 -angle 3 =180°[sum of all angle of a triangle ]

THEREFORE,

7x +3x +90°=180°

10x=180°- 90°

10x =90°

x=90/10

x=9

therefore;

angle 1 = 63°

angle 2 = 27°
