∠a is an acute angle in a right triangle. given that cos a=12/13, what is the ratio for sin a? enter your answer in the boxes as a fraction in simplest form

sin A =

Step-by-step explanation:

As per the statement:

∠A is an acute angle in a right triangle.

Given that:

We have to find Sin A:

Using the formula:

Substitute the given values we have;

⇒

⇒

Therefore, the value of sin A as a fraction in simplest form is,

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
