Answer:

The correct answer is  option C

They are complementary angles

Step-by-step explanation:

From the figure we can see two angles <ABC and <LMN,

<u>To find the correct option</u>

From figure we get,

m<ABC = 20°° and m<LMN = 70°

m<ABC + m<LMN = 20 + 70 = 90°

Therefore <ABC and <LMN are complementary angles

The correct answer is option C

They are complementary angles

(HELP ASAP PLEASE AND THANK YOU..)

Hello!

As you can see, two of the triangles that we see that are made from the lengths we are given make up one face of the pyramid. We can use the triangle formula without multiplying by 1/2 to find the length of one face.

30(45)=1350

Now we multiply this by  four to find all of the sides.

1350(4)=5400

We find the area of the square base

30(30)=900

Finally, we add up our lengths.

5400+900=6300

Therefore, our answer is C) 6400 yards²

I hope this helps!
