Answer 1

Answer: (Hypotenuse)2 = (Base)2 + (Perpendicular)2 (2 means square)

(15)2 = (12)2 + (Perpendicular)2

225= 144 + (Perpendicular)2

(Perpendicular)2 = 225-144

(Perpendicular)2= 81

Perpendicular = Root(81)

                         =9

Given Ratio Of Angles = 1:2:3

Let The Common No.be x

Let the no 1x be 90 degree (One Angle Of Right Angle Triangle Is 90 Degree)

90+2x+3x = 180 degree (Angle Sum Property)

90+5x=180

5x=180-90

x=90/5  

x= 18 degree

2x= 2x18

    = 36 degree

3x= 3x18

    = 54 degree

Therefore, Perpendicular Is 9 cm And Angles Are 90 degree, 36 degree, 54 degree.
