Find the value of x and y of the equilateral triangle

x = 12

y = 30

Step-by-step explanation:

We know:

All sides of equilateral triangle are equal:

= > 3 x + 8 = 4 x - 4

= > 8 + 4 = 4 x - 3 x

= > x = 12

Also, we know all angles of equilateral triangle is 60. And their sum is 180.

= > 2 y = 60

= > y = 30

Hence we get required answer!

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

this is answer of 144 cubic meters
