Sin60 =b/10
<span>√3/2 = b/10
</span>b = <span>√3 / 2 (10)
</span>b = 5<span>√3
</span>
d^2  = 10^2 - (5√3)^2
d^2 = 100 - 75
d^2 = 25
d = 5

sin30 = b/a
1/2 = 5√3  / a

a = 5√3 (2)
a = 10√3

c^2 = (10√3)^2  -  (5√3)^2
c^2 = 300 - 75
c^2 = 225
c = 15

so
a =10√3,  b = 5√3, c = 15,d = 5
answer is

I need help on all these 3 questions plz
DIA [1.3K]

Answer:

  1. Circumference
  2. Area
  3. Circumference

Step-by-step explanation:

Circumference would be if the situation is asking for the amount of something around the edge. For example, the number of tiles to be placed around the swimming pool would be asking for circumference.

Area would be if the situation is asking for the amount of something spread through the entire item. For example, the amount of water total in a swimming pool would be asking for area.

Hope it helps!

Answer:

m = \frac{-y+x}{2}

Step-by-step explanation:

2m - x + 3y = 2y

Take -x and +3y on the other side of the equal to sign:

2m = 2y +x-3y

Now solve for y:

2m = -y +x

Take 2 one the other side of the equation:

m = \frac{-y +x}{2}

Hope this helps :)
