i need help with 3 (along with 3a-c) i am confused on what to do with the numbers that are in degrees...

iVinArrow [24]

Answer:

The answer to your question is below

Step-by-step explanation:

Let p = $\frac{cos x + siny}{\sqrt{w^{2} - z}}$

x = 36°

y = 18°

w = 29

z = 21.8

- Substitution

p = $\frac{cos 36 - sin 18}{\sqrt{29^{2} - 21.8}}$

- Simplification

p = $\frac{0.809 - 0.309}{\sqrt{841 - 21.8}}$

p = $\frac{0.5}{\sqrt{819.2}}$

p = $\frac{0.5}{28.622}$

a) Result

p = 0.017469281

b) Three significant figures

p = 0.017

c) Scientific notation

p = 1.7 x 10⁻²

a = 1.7 k = -2

The temperature is 58° F. It gets warmer by h degrees and reaches to 65° F. Find h.

Aleks [24]

Answer:

h = 7 degrees

Step-by-step explanation:

To find <em>h</em>, we know that it is positive because it increases in value, not decreases:

h = 65 - 58

h = 7

As an estimation we are told £3 is €4.<br> Convert £33 to euros.

Triss [41]

Answer:

44 euros

Step-by-step explanation:

if the ratio between an english pound and a euro is 3 to 4 respectivley, the ratios will hold true for any number. Since 33/3 = 11, we can stratigically multiply by 1,

3/4 = (3/4)(11/11)

so the ratios would be the same, multiplying, you would get 33/44, which means 33 pounds for 44 euros

I’ve never been so confused, this is due in a few minutes, pls help if you can!

Given:

m(ar QT) = 220

m∠P = 54

To find:

The measure of arc RS.

Solution:

PQ and PT are secants intersect outside a circle.

<em>If two secants intersects outside a circle, then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs.</em>

$$\Rightarrow \angle P = \frac{1}{2} (m \ ar (QT) - m \ ar (RS ))$

$$\Rightarrow 54 = \frac{1}{2} (220- m \ ar (RS ))$

Multiply by 2 on both sides.

$$\Rightarrow 2 \times 54 = 2 \times \frac{1}{2} (220- m \ ar (RS ))$

$$\Rightarrow 108= 220- m \ ar (RS )$

Subtract 220 from both sides.

$$\Rightarrow 108-220= 220- m \ ar (RS )-220$

$$\Rightarrow -112= -m \ ar (RS )$

Multiply by (-1) on both sides.

$$\Rightarrow (-112)\times(-1)= -m \ ar (RS )\times(-1)$

$$\Rightarrow 112= m \ ar (RS )$

The measure of arc RS is 112.
