Can someone please help me with this? What would be the measure of angle R to the nearest tenth?

Answer:

Step-by-step explanation:

There are two ways to do this.

1. You could make an accurate diagram and measure R. This works but the computer won't like it. However you will know if you are correct. An answer ± 2 degrees would tell you that you are likely correct.

2. The second way is to find <C. Similarity guarantees that <C and <R are equal. The adjacent side to angle C is the second longest line. The second longest line in PQR is the adjacent side of <R.

Naturally we will use the second method, but you ought to try the first method. It's cumbersome but it will teach you how to read the values of triangles to make clear the trig functions.

Tan(C) = opposite over adjacent

Tan(C) = 7 /  9

Tan(C) = .77777777...

<C = tan-1(0.7777777...)

<C = 37.87

<C = 37.9

The diameter of Jupiter is 142.984 Km. The surface area of Saturn is 59.9% the surface area of Jupiter. What is Saturn's diamete
Otrada [13]
Suppose that both planets are spherical. radius of Saturn =142984/2=71,492

Area of Jupiter = 4πr² ==>4π(71,492)² =6.4228 x 10^10

Area of Saturn ==>(6.4228 x 10^10)x(0.599) ==>3,84726 x 10^10

Radius of Saturn = 4πr² =3,84726 x 10^10==> r²=3,0219 x 10^10
and r √(,0219 x 10^10) = 174.000 km & D = 384,000 km

Answer:

each bottle of juice costs $2.34

Step-by-step explanation:

2.74+10x=26.14

10x=26.14-2.74

10x=23.40

x=23.40/10

x=2.34

X⁴+5x²-6=0 solve for x
Snowcat [4.5K]
Let u = x², then we would have u² + 5u - 6 = 0

From here, we can factor it and get us (u-1)(u+6) = 0

So our solution for u is u = -6 or 1.

Now substitute u back to x².

x² = -6 or 1

x = ±√(-6) or ±√1

Since ±√(-6) is not real number, we ignore it.

Which leave us x = ±√1 = <span>±1

So our real solution is x = -1 or 1.</span>

peggy practices her gymnastics routine for a total of 21 hours . each practice session is 1 3/4 hours . how many practice sessio
algol [13]
Peggy has 12 practice sessions

The first step is finding the unit rate. We can do this by evaluating

21/1.75 divided by 1.75/1.75.
When you divide the two, you get 12.

To check your work you do 12(1.75) and you will get 21
