The two figures shown above are congruent. Identify the corresponding sides and angles.

nasty-shy [4]

Answer:

AB = RS , BC = SP , CD = PQ , AD = RQ

m∠A = m∠R , m∠B = m∠S , m∠C = m∠P , m∠D = m∠Q

Step-by-step explanation:

∵ ABCD congruent to RSPQ

∴ AB = RS , BC = SP , CD = PQ , AD = RQ

∴ m∠A = m∠R , m∠B = m∠S , m∠C = m∠P , m∠D = m∠Q

Answer:

We get the value of x: x= 2

Step-by-step explanation:

Since the triangles are similar, the ratios of the lengths of corresponding sides are same.

We can use proportions to find the value of x

The proportion will be:

$\frac{BD}{DA}=\frac{BE}{EC}$

Now putting there values we can find value of x

We have:

BD = 6, DA = 4, BE = x+1, EC =x

Putting values

$\frac{BD}{DA}=\frac{BE}{EC}\\\frac{6}{4}=\frac{x+1}{x} \\Cross\:Multiply\\6x=4(x+1)\\6x=4x+4\\6x-4x=4x+4-4x\\2x=4\\x=\frac{4}{2}\\x=2$

So, we get the value of x: x= 2

If the volume of the pyramid shown is 360 inches cubed, what is its height?

dimaraw [331]

Answer:

9 inches

Step-by-step explanation:

The formula for the volume of a rectangular pyramid is $V = \frac{1}{3}(l*w*h)$

Here we have volume (V), base (L), and width (W)
V = 360 in³, L = 12 in, W = 10 in

We need to manipulate the volume equation to solve for the height (H)

First we need to multiply both sides by 3 to get rid of the fraction: 3V = L×W×H
Then we need to divide both sides by (L×W) to get: $\frac{3V}{lw} =h$

Now we can plug in the given values:

$\frac{3(360in^{3}) }{(12 in)(10in)} =\frac{1080in^{3} }{120in^{2} } = 9in$
The height is 9 inches
