Answer:

Step-by-step explanation:

It would be B. since both triangles are right triangles. They also are on the same line. So neither of them are at a different angle.

Now to verify that this is correct, we need to eliminate some of the other answers.

Let's start with A.. Congruent means that they are the same shape and size and can be mirrored/backwards. These triangles are the same shape and mirrored but it IS NOT the same size. This means we can eliminate answer A..

Now answer C.. As originally stated, the triangles are similar because they are both right triangles, but they have the same slope since they are on the same line. The line is not changing so the slope will not change either.

And finally answer D.. Answer D. has been proven wrong from the answers B. and C., so we can eliminate it.

This means all the answers are eliminated but B.

Step-by-step explanation:

Remember when expanding radicals,

$\sqrt{ab} = \sqrt{a} \times \sqrt{b}$

When expanding radicals into two radicals, we don't let our radicand have two negative answers.

$i = \sqrt{ - 1}$

${i}^{2} = - 1$

We don't do this

$(\sqrt{ - 1} ) {}^{2} = \sqrt{ - 1 \times - 1}$

$- 1 = \sqrt{1}$

$- 1 = 1$

Margie has a $50.00 budget to purchase $45.00 pair of boots. If there is an 8% sales tax rate then how much under budget will Ma

LuckyWell [14K]

She will be $1.40 under budget.

8% = 8/100 = 0.08

Adding this to 100% of the price of the shoes, we get 108% = 108/100 = 1.08.

We multiply the price of the shoes by this:
45*1.08 = 48.60

Subtract this from 50:
50 - 48.60 = 1.40

East of Star, the railroad tracks intersect highway 23o as shown above. If 1=133 , find 2.

GrogVix [38]

Hi there.

These two angles sum up to be 180 degrees, so they are supplementary angles. Now, since these angles sum up to 180 degrees (to form a straight line), we only have to subtract 133 from 180 to find angle 2's measurement.

180 - 133 = 47

Angle 2's measurement is 47 degrees.

Voila!

I hope this helps! Have a great day. :)

Find the surface area. round to the nearest hundredth when necessary.

Dmitry_Shevchenko [17]

Answer:

The surface area of the cuboid is 648 m^2

Step-by-step explanation:

What we have here is cuboidal in outlook

By using the formula for the surface area of a cuboid, we can get the surface area of the shape

mathematically, we have the surface area of a cuboid as follows;

2(lb + lh + bh)

where l is the length, b is the breadth (width) and h is the height

We can have the length as 9 m, the width as 9 m and the height as 13.5 m

Substituting these values, we have the surface area of the cuboid as;

A = 2(9(9) + 9(13.5) + 9(13.5))

A = 2(81 + 243)

A= 2(324)

A = 648 m^2
