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
D. last choice

Convert the following in standard form : -4x=4y-52
goldenfox [79]
The standard form of any linear equation with two variables is ax+by=c, where a, b, and c are constants. To convert this equation to standard form, simply subtract 4y from both sides to get

-4x-4y=-52

We could leave it in this form, though, in this case, it might be better at if we multiplied both sides by -1 to get

4x+4y=52
