Can a triangle be formed given three angles with measures 20 degrees 110 degrees and 40 degrees

Fredrick designed an experiment in which he spun a spinner 20 times and recorded the results of each spin

In triangle opq right angled at p op=7cm, oq-pq=1 determine the values of sinq and cosq

1. if we have 3 babies what is the probability they’re going to be all boys? 2. if we roll 2 die at the same time what is the probability of getting less than 10 on the first roll and a 5 on the second roll 3. if we have 3 babies what is the probability their is going to be 2 girls? 4. if we have 3 babies what is the probability of having no more than 1 girl? 5. it we have 3 babies and then have another 3 babies what is the probability of us having at least 1 boy and then having all girls?
