X=15degrees
The angle measurements are 30, 30, and 120 so it is an isosceles
24.5x.18=4.41
$4.41 is how much you save with the discount. You subtract this amount from the regular price.
24.5-4.41=20.09
The sale price of the item should be $20.09
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.
