Question

HI APOR, right-angled at Q, PQ=3 cm and PR =6 cm Determine ZP and ZR.​

Answer 1

Answer:

hey here is your solution and also refer the reference diagram uploaded by me above for better understanding

pls mark it as brainliest

so here we go

Step-by-step explanation:

now here angle q=90

thus triangle pqr is a right angled triangle

now pq=3 and pr=6 (given)

so now sin r=opposite side/hypotenuse

=pq/pr

=3/6

=1/2

thus sin r =1/2

now we know that sin 30=1/2

hence angle r=30

now in triangle pqr

apply angle sum property of triangle ,,so we get

angle p+q+r=180

angle p+90+30=180

=180-120

therefore angle p=60

hence remaining angles of triangle pqr are

30 and 60 degree

such that angle p=60 angle r=30 degree
