Help please ill give you brainlest<br> Is this correct??

Most of those are correct but the ones that are not are, (15+8 divided by 4-6) as division comes first. 6x3-8 as multiplication comes before subtraction. And 2/3+4x2, multiplication comes before addition. So change those couple up and you got it.

HELP!!! Find the exact value of <br> cos A in simplest radical form.
Galina-37 [17]

Answer:

cos A = 9/41

Step-by-step explanation:

cosine is a function that puts together the ADJACENT side of a triangle in a ratio with the HYPOTENUSE.

So from angle A the side length 9 is right next to A so it is the ADJACENT side. The HYPOTENUSE is the longest side ,that is the side length 41.

so cos A = ADJ/HYP

cos A = 9/41

It could be that the directions were confusing bc they said simplest radical form. Many, but not all right triangles have one or more sidesides that have a radical as part of their measure. This triangle doesn't. If you get a radical in the denominator of a ratio, be sure to rationalize so that there is no radical on the bottom.
