<span>The side opposite the 30 degree angle is half of the hypotenuse.
a^2 + b^2 = c^2  =>

a^2 + (c/2)^2 = c^2
12^2 + c^2/4 = c^2
4*12^2 + c^2 - 4c^2 = 0 
576 -  3c^2 = 0 
- 3c^2 = - 576
c^2 = 192
c = 8√3

Please help me with this. Just have to write the equation. If you can solve, then you get brainliest guaranteed!
Temka [501]

x = player1

y = player 2

z = player 3

y = 2x  or 1/2 y =x

y = z-10  or z = y+10

x+y+z=70

substitute x= 1/2 y and z = y+10 into the above equation

1/2y + y + y+10 = 70

2.5 y + 10 = 70

subtract 10 from each side

2.5 y = 60

divide by 2.5 on each side

y = 60/2.5

y =24

x = 1/2 y

x = 1/2 *24 = 12

z = y+10 = 24+10 = 34

The three players scored 12, 24, 34

Henri had a plum tree. The first week it was 15 feet. 2 weeks after that is was 22 feet and 2 more weeks later is was 36 feet. w
Alex

Answer:

The equation of tree's growth is given as : C(n)   =  15 + 7 n  ,

n = pair of weeks, n = 2, 4, 6 , 8 , ....

Step-by-step explanation:

Here, the initial height of the plum tree =  15 ft

⇒h (0)  = 15 ft

Now, after two weeks the tree is 22 ft

⇒h (2)  = 22 ft

Now,the growth of tree in 2 weeks

=  Height after 2 weeks -  Initial height of tree

= 22 ft  -  15 ft = 7  ft

So, the plum tree grows 7 ft in 2 weeks

⇒ The plum tree grown (7/2) ft in 1 week.

Also, the growth of tree in next 2  weeks  =  36 ft

So, the growth of tree in next 2  weeks

= Height after 4 weeks - Height after 2 weeks

= 36 ft  - 22 ft  = 14 ft

So, the tree grows 14 ft in next two weeks.

⇒ The tree grows 7 ft in next 2 weeks.

hence, the complete growth of each week is given as:

15 ft , 18.5 ft ,  22 ft ,  29 ft , 36 ft

So, the equation of tree' growth is given as : C(n)   =  15 + 7 n

Here, n = Pair of weeks, n = 2, 4, 6 , 8 , ....
