Question

please give me any 1 from this 2 questions please ​

Answer 1

Answer:(2)

here,

∠X+∠Y+∠Z=180............[SUM OF ANGLES OF TRIANGLE]

or,(a+30)+90+a=180

or,2a=60

∴a=30

so,∠X=(a+30)=60

    ∠Z=a=30

now,

sin(∠Z)=XY/XZ

or,XY=XZ*sin(∠Z)

        =24*sin30

        =12

by pythagoras theoren

XZ²=XY²+YZ²

or,YZ=√(XZ²-XY²)

        =√(24²-12²)

        =12√3

so, XY=12, YZ=12√3
