Answer: 6.6

Step-by-step explanation: To round, look to the number in the place value beside the place value given. In yours, look to the hundredths place because it's to the right of the tenths place. In the number is 5 or more, add one to the given place value. 4 or less, leave it alone and as is. After the given value, make everything a zero.

Can someone please help me with this

Answers:

x = 3
CD = 21
DE = 16
CE = 21

=============================================================

Explanation:

The congruent base angles are D and E. Opposite those angles are the sides CE and CD. These opposite sides are the same length.

CE = CD

16x-27 = 4x+9

16x-4x = 9+27

12x = 36

x = 36/12

x = 3

This x value then leads to the following:

CD = 4x+9 = 4*3+9 = 12+9 = 21
DE = 7x-5 = 7*3-5 = 21-5 = 16
CE = 16x-27 = 16*3-27 = 48-27 = 21

We see that CD and CE are both 21 units long, which helps confirm we have the correct x value.

Based on the knowledge of trigonometric expressions and properties of trigonometric functions, the value of the sine function is equal to - √731 / 30.

<h3>How to find the value of a trigonometric function</h3>

Herein we must make use of trigonometric expressions and properties of trigonometric functions to find the right value. According to trigonometry, both cosine and sine are negative in the third quadrant. Thus, by using the fundamental trigonometric expression (sin² α + cos² α = 1) and substituting all known terms we find that:

$\sin \theta = -\sqrt{1 - \cos^{2}\theta}$

$\sin \theta = - \sqrt{1 - \left(-\frac{13}{30} \right)^{2}}$

sin θ ≈ - √731 / 30

Based on the knowledge of trigonometric expressions and properties of trigonometric functions, the value of the sine function is equal to - √731 / 30.
