Question

please tell me this answer fast ​

Answer 1

Answer:

ist by angle sum prop of triangles we get

in traingle abc

90+30+x=180

x=180-120

x=60

now in triangle pqr

60+90+x=180

x=180-150

x=30

hence,

<bac=< rpq

and <acb=<qrp

In traingle abc and traingle pqr

<bac=< rpq ( proved above)

AC=PR (given)

<acb=<qrp (proved above )

therefore triangle abc is congruent to pqr by ASA rule
