Answer:
The answer to your question is below
Step-by-step explanation:
sin Ф = Opposite side / hypotenuse
cosФ = Adjacent side / hypotenuse
tan Ф = Opposite side / Adjacent side
For this right triangle
Opposite side = 5
Adjacent side = 12
Hypotenuse = 13
Then,
sin Ф = 5/13
cos Ф = 12/13
tan Ф = 5/12
Answer:
B. -9
Step-by-step explanation:
3(-9)-6/3=-11
7(-9)-3/6=-11
Answer:
Step-by-step explanation:
Nine has to be taken from 3x a number. This will equal 20.
If sec(A) = 4/3, then the value cot(A) is
The given trigonometric identity is:
.........................(*)
Note that:
.........................(**)
Comparing (*) and (**)
Hypotenuse = 4
Adjacent = 3
Find the opposite using the Pythagoras theorem
Hypotenuse² = Opposite² + Adjacent²
4² = Opposite² + 3²
Opposite² = 4² - 3²
Opposite² = 16 - 9
Opposite² = 7
Opposite = √7
cot(A) = Adjacent/Opposite
cot(A) = 3/√7
Rationalize the expression
