How do i solve this problem? am i supposed to use tan, sin, or cos?

cos(45) * 28 = 14√2 or 19.8

Step-by-step explanation:

You have the hypotenuse and you want to find the adjacent side b. Out of Soh, CaH and ToA, you know it is CaH because you want the adjacent and have the Hypotenuse (a and H).

If you put CaH into a triangle and cover up the A, you will see that it would be C * H. If you put that into a calculator and substitute in the values you get cos(45) * 28 = 14√2

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
