To know when a equation is false, it is simply incorrect. When a equation is true, it will be correct. An open sentence is a statement which contains a variable, and becomes either true or false, depending on the value that replaces the variable. Hope this helps!

What are the ratios for SIN A and COS A

miskamm [114]

Answer:

Step-by-step explanation:

A good trick for trigonometric functions is to remember SOHCAHTOA:

Sin=Opposite over Hypotenuse

Cos=Adjacent over Hypotenuse

Tan=Opposite over Adjacent

The red arrows on the attachment indicate where opposite, hypotenuse, and adjacent are for angle A.

So in this case, the sin of angle A (opposite over hypotenuse) would be $\frac{24}{26}$ and cos A (adjacent over hypotenuse) would be $\frac{10}{26}$ .
