The figure shown at the right is known as pascal triangle

step-by-step explanation: the answer for wha if rt is 10 centimeters long, and wha is st? it’s 6

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

if you're trying to figure out how much each ounce cost it would be 0.20
