Answer: C, 93m^2

Step-by-step explanation:

first step is to find the surface area of the base. it's 3x3, so that would be 9m^2. the sides of the rectangular prism are 5x3, so one side is 15m^2. there are 4, so 15x4=60m^2. now for the top, which is a triangular prism. each side has a height of 4 and a base of 3. the area of a triangle is 1/2bh, so 1/2(3)(4), which is 6. 4 of these makes 24 m^2. add up all of final numbers to get 9+60+24. this comes to 93m^2, or C.

Easy question please answer :)))
Burka [1]

Answer:

Angle CED must also measure 60°. 

Because angle m is shown to be congruent to angles ABC and CDE, this means that angle m has a measure of 60 degrees.

There can only be 180 degrees in a triangle, so the measure of angle ACB must be 180-60-60, which equals 60 degrees.

Using the Vertical Angles Theorem, the measure of angle ACB is the same as the measure of angle CED.

Therefore, angle CED measures 60°.

Step-by-step explanation:

m, because Triangle ABC is similar to triangle EDC

m over 2, because Triangle ABC is congruent to triangle DCE

m + 60 degrees, because Triangle ABC is similar to triangle DCE

120 degrees − m, because Triangle ABC is congruent to triangle DCE

Find the value of x. Then find the angle measures of the polygon.
Minchanka [31]

Answer:

35° , 40° , 105°

Step-by-step explanation:

the sum of the 3 angles in the triangle = 180° , then

3x + x + 40 = 180 , that is

4x + 40 = 180 ( subtract 40 from both sides )

4x = 140 ( divide both sides by 4 )

x = 35

3x = 3 × 35 = 105

the 3 angle measures are 35° , 40° , 105°

What is the volume of the right rectangular prism?
Tamiku [17]

Hi!

Volume = Length x Width x Height

Therefore, V = 5 x 5 x 10

5 x 5 x 10 = 25 x 10 = 250 m^{3}.

Your answer is D, the last one.

Hope this helps! :D
