The "successful" region has half the size of the whole triangle, so by similar triangles, the probability that the area of triangle XYD is at most 12 is 1/4.

Answer:
∠KNC and ∠KMC are right angles
∠MCN = 25°
Step-by-step explanation:
if KM and KN are tangent lines, then they are perpendicular to the radius going through the tangent point, so therefore right angles are:
1. ∠KNC
2. ∠KMC
the outside angle of a circle is equivalent to half the measure of the intercepted arc, so
if ∠MKN = 50°, then ∠MCN = 25°
101 degrees is the answer
Not that sure tbh
Best luck with your studying
Answer:
860.55 mm²
Step-by-step explanation:
The surface area of an hexagonal prism, also known as an octahedron, is given by the following formula (since we have the apothem):
S= 6*b*(a+h)
where b = is the side of the base, a is the apothem length, and h = the height
S = 6 * 8 * (4√3 + 11) = 48 * 17.92812 = 860.55 sq mm
Could have also have used another formula without the apothem:
S =3 * √3 * b² + 6 * b * h
S = 3 * √3 * 8² + 6 * 8 * 11 = 3√3 * 64 + 528 = 332.55 + 528 = 860.55 sq mm
