Question

Q 38: AXYZ is right angled at Y. Find the value of 'p', if XY = pcm, YZ = 28cm and ZX=
35cm.​

Answer 1

Answer:

use pythagorus theorem a2+b2=c2

Step-by-step explanation:

28square+ p2 = 35square

784+p2=1225

1225-784=p2

441=p2

p=21

p=21cm

Answer 2

Answer:

21 cm is the answer, acc. to the question given by you...

Step-by-step explanation:

Acc. to Pythagorean theorem this fig. will be a right triangle

(H)^2 = (P)^2 + (B)^2

(35)^2 = (XY)^2 + (28)^2

1225 = (XY)^2 + 784 cm^2

(XY)^2 = 1225 - 784 cm^2

(XY)^2 = 441 cm^2

(XY) = √441 cm^2

(XY) = 21 cm
