Question

in triangle pqr angle q=90 degree angle r=30 degree if pr is 12 find pq

Answer 1

Answer:the answer is 6

Step-by-step explanation:according the question,sin30` =pq÷pr....so pq =pr×sin30`=12×0.5=6..

Answer 2

Answer:

pq=6

Step-by-step explanation:

in Δpqr, ∠q= 90°

∠r=30°

pr=12 then

sin30=pq/pr

⇒1/2=x/12

⇒2x=12

⇒x=12/2

∴x=6
