Answer:
Formula:(from trigonometry)
Tan(A+B)=(tanA+tanB)/(1-tanA*tanB)
Let A=22 degrees,B=23 degrees
Tan(22+23)=(tan22+tan23)/(1-tan22*tan23)
From trigonometry we know tan45=1
Therefore tan(45)=1=(tan22+tan23)/(1-tan22tan23)
=> 1-tan22tan23=tan22+tan23
=> tan22+tan23+tan23tan22 =1
Hence proved
Answer:
d. 2/9
Step-by-step explanation:
7/8 - 0.85
3/5 - 0.6
5/2 - 2.5
2/9 - 0.222... the two is a recurring number
20 is the tenth digit in the quotient
