Question

XYZ is
a triangle
right angled at z.
if yz = 12 cm, and
xz = 5cm find xy?​

Answer 1

Answer:

Given: ∆XYZ right angled at Z and XY = 13 cm, XZ = 12 cm.

To find: Length of YZ.

According to Pythagoras Theorem,

XY2 = XZ2 + YZ2

132 = 122 + YZ2

169 = 144 +YZ2

169 - 144 = YZ2

25 = YZ2

∴ YZ = √25cm √5x5 = 5 cm

Answer 2

Answer:

by pathagores therom

h square = p2 + b2

h2= 12square + 5 square

h2 = 144 + 25

h square = 169

h= ✓ 163

h= 13

xy = 13
