What is the surface area of the right prism given below?
posledela

Answer: Option D.

Step-by-step explanation:

You can calculate the surface area of this right prism by adding the area of its faces.

You can observe that the faces of the right prism are:  Three different rectangles and two equal triangles.

The formula for calculate the  area of a rectangle is:

A=lw

 Where "l" is the lenght and "w" is the width.

The formula for calculate the  area of a triangle is:

A=\frac{bh}{2}

Where "b" is the base and "h" is the height.

You can observe that the hypotenuse of the each triangle is the width of one of the larger rectangle, then , you can find its value with the Pythagorean Theorem:

a=\sqrt{b^2+c^2}

Where "a" is the hypotenuse and "b" and "c" are the legs of the triangle.

Then, this is:

a=\sqrt{(8units)^2+(15units)^2}=17units

Therefore, you can add the areas of the faces to find the surface area of the right prism (Since the triangles are equal, you can multiply the area of one of them by 2). This is:

SA=(10units)(8units)+(15units)(10units)+(17units)(10units)+2(\frac{(15units)(8units)}{2})\\\\SA=520units^2

Consider the linear equation 2/5x+y=11. will you choose to fix x or y?
sukhopar [10]
Y is the easiest to fix because it has no coefficient, and is therefore the easiest to set on the other side of the equation by itself

I NEED HELP PLEASE DONT SEND ME LINKS TO WEBSITES. ANSWER THE QUESTION HERE THANK YOU.
mote1985 [20]

Answer:

33

Step-by-step explanation:

The two angles add up to 180 degrees because a straight line is 180 degrees

<em>Add both equations and set equal to 180</em>

3m + 138 + 7m +12 = 180

<em>Algebra yeet</em>

<em>Simplify</em>

10m +150 = 180

10m = 30

m = 3

Angle DBC is (7m + 12):

<em>Substitute m = 3</em>

7(3) + 12 = 21 + 12 = 33 degrees
