We can  use the cosine....

cos (12 ° )  =  H / 150       where H is the horizontal distance.....multiply both sides by 150

150 * cos (12°)   = H  ≈  146.7 m

Use the equation 

1 1/2 = (3/4 + 1 + 2 1/2 + x)/4

I'm sure you can figure that out. (Or just use the calculator)

wow...  

product mean multiply

tg15∘⋅tg25∘⋅tg35∘⋅tg85=? help pls

I do not understand what you are asking.

3.456000 × 10⁶

Just use the minus sign.

It is already to the nearest hundredth

Use the Pythagorean theorem: 

a²+b²=c²

a²+15²=17²

a²+225=289 

a²=289-225

a²=74

a=sqrt(74)

The Pythagorean theorem says that:

(leg)² + (other leg)² = (hypotenuse)²

One leg is 15.

The other leg is the missing side.

The hypotenuse is 17.

All you have to do is plug in the right numbers into the right slots.

Can you get that far with it?

\(\sin x = \frac{7}{9} \\ x = \arcsin(\frac{7}{9}) \\ x \approx 51.058^{\circ}\)

The answer to this question also applies to your question:

He's right! I was just gonna post the answer :D

Use the cosine

cos ( 22°)  = x  / 11    multiply both sides by 11

11 * cos ( 22°)  = x  ≈   10.2

11111 1111000100 0111111111 is a PRIME!.

It can be written as the sum of FOUR squares as follows:

n =a^2 + b^2 + c^2 + d^2

a = 962778 878031

b = 311833 920777

c = 255380 357289

d = 147337 778530

Circumference   =  pi * diameter   .....so....

16  =  pi  *   diameter           divide both sides by  pi

16 / pi   = diameter  ≈  5.093 

sin x  =  opp/ hyp  =  sqrt (119)  / 12

cos x   =  adj / hyp  =  5 /12

If you have the length of the radius and the degree of the angle, calculation of the length of an arc is simple.

First, calculate the circumference of the circle using the radius (C = 2 * pi * r). You can multiply the known circumference by the ratio of the angle to the full circle (i.e. degree of arc/360º). The final product is the length of the arc. 

Well you do use a dashed line to show symmetry ....   I guess that is what you mean. 

(6 /25) * 4000  =

what is 28 divided by 5 5/6?

\(28:5\frac{5}{6}=28:\frac{35}{6}=28\times\frac{6}{35}=4\times\frac{6}{5}=\frac{24}{5}=4\frac{4}{5}\)

  !

5 5/6   =   35/6

So

28  /  ( 35/6)  =

(28/1) / (35/6)  =  

(28/1) (6/35)   =    swap denominators

(28 / 35)  *  (6 /1)   =

(4 / 5)   *  ( 6 /1)   =

24 / 5    =

4  4/5
