Question

in angle xyz and angle x and angle z is of 45 then find the length of side of xy​

Answer 1

Answer:

90 degree is the correct

Answer 2

Answer:

In △XYZ,∠Y=90o,∠Z=ao and ∠X=(a+30)o

XZ=24 ...... (Given)

In triangle XYZ,

∠X+∠Y+∠Z=180o

⟹(a+30)o+90o+ao=180o

⟹2a=60o

⟹a=30o

∴∠Z=30o and ∠Y=60o

Now, sin30o=XZXY

⟹21=24XY

⟹XY=12 cm

Also, cos30o=XZYZ

⟹23=24YZ
