Answer:

Option A is correct i.e Area is 56 square centimeter.

Step-by-step explanation:

Given EC = 10cm, AE = 4cm, and m∠EAB = 45°. we have to find the area of kite.

In ΔABE,  ∠EAB = 45°

tan\angle EAB=\frac{BE}{AE}

⇒ tan 45^{\circ}=\frac{BE}{4}

⇒ BE=4 cm

BE=ED=4 cm (one diagonal of kite bisect other)

BD=BE+ED=4+4=8 cm

AC=AE+EC=4+10=14 cm

\text{Area of kite=}\frac{pq}{2}, where p and q are the diagonals

⇒ \text{Area of kite ABCD=}\frac{8\times 14}{2}=56cm^2

Option A is correct.

(c) Find the number of sets where all three cards are the same for exactly $0$ attributes. (d) Find the number of sets where all
Cloud [144]

C. For the first card, there are three ways to choose the number of card.

For the another, there two options, and likewise there's only 1 choice of card. So there are 3 × 2 × 1 = 6 ways that the calculation can be chosen.

Doing this for the other attributes, we get 6 × 6 × 24 × 6 ways. But the order of cards does not count in a set of card, so we divide by 3! 6 * 6 * 24 × 6 ÷ 3! = 864. It means there are 864 sets for part.

D. The cards may have the same number, color, shapess, orshading.

However, also there are 6 × 24 × 6 × 3! = 144 sets of cards, If all the colors are thesame. How ever, also there are 144 sets of cards.

If all the calculation are the same. We get the same number for shape and shadings, so there are 4 × 144 = 576 sets of cards.

what is Probability?

Probability is branches of mathematics concerning numerical descriptions of how to the likely an event is to occurs, or how to the likely it is that a proposition is true. The probability of an event is a numbers between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the events and 1 indicates certain of cards.

Simon's dog jumped into a stream at a 68° angle from the corner of a bridge. simon crossed the bridge and walked downstream to m
artcher [175]

The length of the bridge is 12.12 feet.

The length the dog swam is 32.36 feet.

The situation forms a right angle triangle.

<h3>What is a right angle triangle?</h3>

A right angle triangle has one of its angles as 90 degrees. Therefore, the sides and angle can be found using trigonometric ratios.

The length of the bridge is the opposite side of the triangle and the length the dog swim is the hypotenuse side of the triangle.

Therefore,

Let's find the length of the bridge as follows:

tan 68° = opposite / adjacent

tan 68° = 30 / l

cross multiply

l = 30 / tan 68

l = 12.1212121212

length of the bridge = 12.12 ft

The length the dog swim is as follows:

sin 68°= opposite / hypotenuse

sin 68° = 30 / h

h = 30 / sin 68

h = 32.3561767942

The distance the dog swimmed = 32.36 ft
