Answer 2

Answer:

1) Third side = 3 cm

2) AB = 13 cm

3) Angles are :  36° , 54° , 90°

Step-by-step explanation:

1) Since, the longest side of a right-angled triangle is known as hypotenuse.

Therefore, h=5 cm

let other side be  = a = 4 cm

By Pythagoras theorem,

h²=a²+b²

5*5 = 4*4 + b*b

25 = 16+b*b

b*b = 9

b = 3 cm

2) AC=12 cm

BC = 4 cm

AB=?

Since, the triangle is right angled triangle at C

hence, AB will be triangle's hypotenus

By Pythagoras theorem,

AC² + BC²=AB²

AC*AC + BC*BC = AB*AB

12*12 + 5*5 = AB*AB

144 + 25 = AB*AB

AB*AB = 144 + 25

b*b = 169

b = 13 cm

3) let the ratio be x

since, total sum of angles in a triangle= 180°

therefore,

2x+3x+5x=180°

10 x= 180°

x= 180/10 = 18°

putting value of x in each angle

2x = 2 * 18° = 36°

3x = 3 * 18° = 54°

5x = 5 * 18° = 90°
