Trigonometric functions: what is the value of x?

Mathematics
1 answer:
Airida [17]4 years ago
3 0

Answer:

x ≈ 19.7

Step-by-step explanation:

Using the sine ratio in the right triangle.

sin66° = \frac{opposite}{hypotenuse} = \frac{18}{x} ( multiply both sides by x )

x × sin66° = 18 ( divide both sides by sin66° )

x = \frac{18}{sin66} ≈ 19.7 ( to the nearest tenth )

1) 3x – 2y=-16<br> Write the slope-intercept form of the equation of each line
raketka [301]

Answer:

y = \frac{3}{2} x + 8

Step-by-step explanation:

The equation of a line in slope- intercept gorm is

y = mx + c

Given

3x - 2y = - 16 ( subtract 3x from both sides )

- 2y = - 3x - 16 ( divide all terms by - 2 )

y = \frac{3}{2} x + 8 ← in slope- intercept form

I NEED HELP PLEASE DONT SEND ME LINKS TO WEBSITES. ANSWER THE QUESTION HERE THANK YOU.
mote1985 [20]

Answer:

33

Step-by-step explanation:

The two angles add up to 180 degrees because a straight line is 180 degrees

<em>Add both equations and set equal to 180</em>

3m + 138 + 7m +12 = 180

<em>Algebra yeet</em>

<em>Simplify</em>

10m +150 = 180

10m = 30

m = 3

Angle DBC is (7m + 12):

<em>Substitute m = 3</em>

7(3) + 12 = 21 + 12 = 33 degrees

Explain how 49. 567 is done in fraction form
pav-90 [236]
<span>= 49567/1000

</span>rite the decimal number as a fraction
(over 1)
49.567 = 49.567 / 1

Multiplying by 1 to eliminate 3 decimal places
we multiply top and bottom by 3 10's

Numerator (N)
N = 49.567 × 10 × 10 × 10 = 49567
Denominator (D)
D = 1 × 10 × 10 × 10 = 1000

N / D = 49567 / 1000

Simplifying our fraction
