Answer:
Becky
Step-by-step explanation:
Look at it.... i mean 21:35 is the greatest in fraction, decimal and percentage.
Solution:
(tanx + tany)/(1-tanxtany) is equal to the formula of tan(x+y)
sinxcosy + cosxsiny = is equal to the formula of sin(x+y)formula
cosxcosy - sinxsiny) = is equal to the formula of cos(x+y)
So this means that
tan(x+y) = sin(x+y)/cos(x+y)
Angle Y = 104 degrees
Angle X = 70 degrees
