Solve for X. (nearest WHOLE degree)

Mathematics
1 answer:
MariettaO [177]3 years ago
4 0

Answer:

<h2>x = 32°</h2>

Step-by-step explanation:

To solve for x we use sine

sin ∅ = opposite / hypotenuse

From the question

38 is the hypotenuse

20 is the opposite

So we have

sin x = 20/38

sin x = 10/19

x = sin-¹ 10/19

x = 31.75

<h3>x = 32° to the nearest degree</h3>

Hope this helps you

dezoksy [38]

Answer:

y = 5.4x + 23.5

Step-by-step explanation:

Since the service charges $23.50 for every hour, you have to multiply x by 23.5 like this: 23.5

There is a flat fee of $23.50, so you have to add 23.5 on top of that like this: 5.4x + 23.5

All of this has to add up to y; 5.4x + 23.5 = y

Area of the large semicircle

= \pi{r}^{2}  \div 2

=  \frac{22}{7}  \times 12 {}^{2}  \times  \frac{1}{2}

=  \frac{11}{7}  \times12 \times 12

=  \frac{11}{7}  \times 144

= 226.28

Area of the small semicircle

= \pi  {r}^{2}  \div 2

=  \frac{22}{7}  \times 6 {}^{2}  \times  \frac{1}{2}

=  \frac{11}{7}  \times 6 \times 6

=  \frac{11}{7}  \times 36

= 56.57

Area of the figure

= 226.28 - 56.57

= 169.71 {cm}^{2}
