In the right triangle shown in the diagram below, what is the value of x to the nearest whole number? (a)12
(b)14
(c)21
(d)28

(c) 21

Step-by-step explanation:

I think the drawn was misprinted. In the picture attached, the correct drawn is shown.

From definition:

cos(β) = adjacent/hypotenuse

For angle = 30°, the adjacent side is x. On the other hand, the hypotenuse of the triangle is 24 units long. Replacing this information into the equation:

cos(30°) = x/24

x = cos(30°)*24

x ≈ 21

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'.

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it
