Answer:
Step-by-step explanation:
Tan 145 = - 0.7002
Tan 85 = 11.43
Tan 145 + tan 85 = 10.7298
1 - tan(145)* tan(85) = 9.003
(Tan(145) + Tan(85)) / (9.003)
= 10.73 / 9.003
= 1.1918
I misread the question. If you mean
(Tan145+tan85) /1-tan145*tan85 (brackets are really important here)
then the answer is
Tan(145 + 85)
= Tan(230)
= 1.1918
Answer:
nope
Step-by-step explanation:
Water is tasteless and odorless
Answer:
C and D
Step-by-step explanation:
Given
(3x - 5)² = 19 ( take the square root of both sides )
3x - 5 = ± 
( add 5 to both sides )
3x = ± + 5 ( divide both sides by 3 )
x = 
x = 
→ C
x = 
→ D
You solve this problem via PEMDAS (Parentheses Exponents Multiplication Division Addition Subtraction.)
To start you simplify everything inside parentheses.
9+3*5+5^2
Then you simplify the exponents.
9+3*5+25
Next, you simplify the multiplication signs.
9+15+25
Then you simplify all the addition signs from left to right.
24+25
49
