3 0

Answer:

=> R = ~25 deg

Step-by-step explanation:

Apply the sine theorem:

PQ/sinR = RP/sinQ

=> sinR = (PQ/RP)*sinQ

            = (20/36)*sin(50 deg)

            = 0.4256

=> R = ~25 deg

Hope this helps!

Do these ratios make a proportion? 4:10 and 6:15<br><br> I NEED THIS ASAP!!! Thanks!
Sonbull [250]

To see if these ratios make a proportion let us first change them into fractions

= 4:10 = 4/10 = 4 ÷ 2 / 10 ÷ 2 = 2/5

= 6:15 = 6/15 = 6 ÷ 3 / 15 ÷ 3 = 2/5

= Since both these ratios are getting simplified into a same fraction , they are proportional .

Therefore , 4 : 10 :: 6 : 15 ( 4 : 10 is proportional to 6 : 15 )
