Yes because it is a square and if you rotate a square 90 degrees it will stay the same shape

Find the measure of AC.

alexira [117]

Answer:

AC = 23 so it be D

Step-by-step explanation:

plug AC = DF ---> 21x-19 = 3x+17

sub. 3x by both sides --> 18x-19 = 17

add 19 to both sides --> 18x = 36

divide both sides by 18, x = 2

plug x back into 21x-19 to find AC

21(2) - 19

42 - 19 = 23

Round to the nearest tenth.

Answer:

8.2 units

Step-by-step explanation:

Given that the only information for our triangle are 2 sides and 1 angle, we must use the Law of Cosines to find side BC

<u />

<u>Recall the Law of Cosines</u>

<u /> $a^2=b^2+c^2-2bc\cdot cos(A)$

<u>Identify angles and sides</u>

<u /> $m\angle A=23^\circ\\a=BC=?\\b=AC=14\\c=AB=6$

<u>Solve for side "a"</u>

<u /> $a^2=b^2+c^2-2bc\cdot cos(A)\\\\a^2=14^2+6^2-2(14)(6)\cdot cos(23^\circ)\\\\a^2=196+36-168cos(23^\circ)\\\\a^2=222-168cos(23^\circ)\\\\a=\sqrt{222-168cos(23^\circ)}\\ \\a\approx8.2$

Therefore, the length of line segment BC is about 8.2 units

a napkin has an area of 5 square inch . what is the side length of the napkin to the nearest hundredth of an inch?

mart [117]

The side length is 2.24 inches.

The area of a square is given by s²; we have
s² = 5

To find the value of s, we take the square root of each side:
√s² = √5
s = √5 = 2.236 ≈ 2.24
