Find the surface area (the triangle are right triangles).
Igoryamba

Answer:

67.5

Step-by-step explanation:

Well area of a triange is 1/2bh so we can find the side closest to us by doing

1/2(3x4) which is 12

the other side would be 1/2 (3x5) which is 7.5

the bottom side would be 1/2(8x4) so 16

and 1/2 (3x8) so 12

1/2 (8x5) so 20

add those together to get 67.5

Hope this helped ya!

Sergio [31]
3x+3=3y ⇒ 3y-3x=3 ⇒3(y-x)=3 ⇒ y-x=1
2x-6y=2 ⇒ 2(x-3y)=2 ⇒ x-3y=1

We must to collect two equations.
x's is lost;
y-3y=2
-2y=2
y=-1   ; x-3.(-1)=1  
⇒ x=-2
