The two triangles (ABC and ADE) can be shown to be similar (which I'll do below). Their corresponding parts are also similar. 
Step One
Prove Similarity.
A is common to both triangles              Construction
<ABC = <ADE                                       Given as right angles.

By the AA Theorem both triangles are similar.

Step Two
Find x

AD is to AB as DE is to x
AD = 3 + 4 = 7
AB = 3
DE = 6
7 / 3 = 6/x Cross multiply
7x = 3 * 6
7x = 18 Divide by 7
x = 18/7
x = 2.571 <<<<< answer

Find the area of the shaded sector.
Vladimir [108]

Given that,

Radius of the circle, r = 8.91 cm

Angle, \theta=81^{\circ}

To find,

The area of minor sector.

Solution,

The formula for the area of minor sector is given by the formula as follows :

A=\dfrac{\theta}{360}\times \pi r^2\\\\A=\dfrac{81}{360}\times \pi \times (8.91)^2\\\\A=56.11\ \text{cm}^2

So, the area of the shaded sector is 56.11\ \text{cm}^2.

The dimensions of a right triangle are shown in the diagram.
ryzh [129]

Answer:

18.4 cm

Step-by-step explanation:

For this problem, you would use <em>Pythagorean Theorem </em>or a^2+b^2=c^2. Don't forget that the c in the formula is always your hypotenuse or the longest side of the triangle. The a and the b are always the legs of the triangle. (It doesn't matter which leg is which letter) The hypotenuse is also always across from the 90 degree angle. <u>Picture the 90 degree angle as an arrow pointing to the hypotenuse.</u>  In this case, the hypotenuse (or c) is 20.7 cm. Now all you have to do is plug and chug! I hope this helps you and thanks for asking your question!!

The answer to number 5 is 16 because if 1/8 goes per bag then every one pound is stretched into eight bags and you multiply by two for the two pounds and get 16 bags for number six you just divide 1/4 by 3 and get 0.0833 pounds per child
