Given:
In a right angled triangle ABC the perpendicular and the base measure 3 cm.
To find:
The hypotenuse and three trigonometric ratios.
Solution:
Pythagoras theorem:

Use Pythagoras theorem in triangle ABC.




The three trigonometric ratios are



Similarly,



And,



Therefore, the hypotenuse is
cm and three trigonometric ratios are
.
For the first one it would be C and the second one would be B
Answer:
or 0.0000128
Step-by-step explanation:
Add the exponents together
-4+-3=-7
It is true because a rational function is defined as those functions where the variable is placed in the denominator, which must be restricted, because all denominators cannot be equal to zero, other wise it would be undetermined
