Can I get some help please

Mathematics
1 answer:
Katen [24]3 years ago
4 0

Answer:

Step-by-step explanation:

First of all we have to use cos.

cos (30) is  √3/2

so (7√3)/(√3/2)

7√3 * 2/√3 = 14√3/√3

(14√3 * √3 )/ 3

42/3 = 14

<u>I AM ASSUMING THIS QUESTION IS NON CALC.</u>

The answer should be 14.

Yuki888 [10]

Answer:

Square shaped = 27 cubic inches , Rectangular shaped = 3LW cubic Inches

Step-by-step explanation:

      V = Length * Length * Length = L^{3}

      V = 3 * 3 * 3 = 27 inch^{3}

Can someone please help?

B- They are always congruent. Congruent means in agreement or harmony. But in this case, identical in form. Parallelograms are parallel on both sides, which makes them have congruent sides. 
P.S.- This is elementary level, no offense.
