Answer:

x = 1 and y = -2

Step-by-step explanation:

Given that,

2x-3y = 8 ..(1)

4x+3y = -2 ..(2)

Add equation (1) and (2),

2x-3y+4x+3y = 8+(-2)

6x = 6

x = 1

Put the value of x in equation (1).

2-3y = 8

2-8 = 3y

-6 = 3y

y = -2

Hence, the value of x is 1 and that of y is -2.

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
