Question

find the value of tanB and cosecB from the given right angled triangle if XZ=13 and YZ=12

Answer 1

Answer:

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:

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
