In this triangle, the product of sin b and tan c is _, and the product of sin c and tan b is_.
its 42 degrees
its a proportionate line so it has the same angle on both sides.
the answer is b. m∠ pos + m∠ por = 180
because if you already know that m∠poq equals 90 because it is a right angle
then all you have to do is take 90 from 180 which is 90 then divide 90 by two which is 45
now you have the measurement for the two acute angles 45
which makes m∠pos = 45 and m∠qor =45
now you have to add 90 and 45 and 45 all together then you will have 180
