Answer:

Hello,

What is tan 30°?

tan(30^o)=\dfrac {\sqrt{3} }{3}

Step-by-step explanation:

sin(30^o)=\dfrac{1}{2} \\\\cos(30^o)=\dfrac{\sqrt{3} }{2} \\\\\\tan(30^o)=\dfrac{sin(30^o)}{cos(30^o)} \\tan(30^o)=\dfrac{\dfrac{1}{2} }  { \dfrac{\sqrt{3} }{2} }\\\\ =\dfrac {1*2}{2*\sqrt{3} }\\\\ =\dfrac {\sqrt{3} }{3}

∠A=8x+6 ∘ start color #11accd, angle, A, end color #11accd, equals, start color #11accd, 8, x, plus, 6, degrees, end color #11ac
zvonat [6]

Answer:

x = 8

B = 70

Step-by-step explanation:

Given

A = 8x + 6

B = 4x + 38

Require

Determine x and <B

Missing in the question: A and B are vertical angles

For vertical angles A and B,

A = B

Substitute values for A and B

8x + 6 = 4x + 38

Collect Like Terms

8x - 4x = 38 - 6

4x = 32

Solve for x

x = 32/4

x = 8

To solve for B, substitute 8 for x in B = 4x + 38

B = 4 * 8 + 38

B = 32 + 38

B = 70

Use a common denominator to determine whether the ratios form a proportion.
Marysya12 [62]
Well, the common denominator of6 and 15 would be three so you would get 2 and 3

the common denominator of 30 and 80 would be 10 and it would equal 3 and 8

The length of a planet's orbit around a star is approximately 17,650,000 km.
daser333 [38]

Answer:

1150 km/hr

Step-by-step explanation:

Formula for Average Speed is given as = Distance in Kilometers/ Time in Hours

In the question we are given the following parameters.

The length of a planet's orbit around a star = Distance = 17,650,000 km.

Time taken to complete a full orbit = 640 Earth days

Step 1

We need to convert the time in days to hours

1 Earth day = 24 hours

640 Earth days =

We cross multiply

640 Earth days × 24 hours

= 15360 hours.

Step 2

Average Speed = Distance in Kilometers/ Time in Hours

Average Speed = 17,650,000 km. /15360 hours

Average Speed = 1149.0885417 km/hr

Approximately to 3 significant figures=

1150 km/hr

Therefore, the planets average speed in kmh-1 to 3sf is 1150 km/hr
