Your answer would be x = 12

The triangle sum theorem states that the 3 angles in a triangle equal 180.

Since we have a 90 degree angle shown, we can add it to the other two and set it equal to 180.

30+90+6x-12=180
108+6x=180
6x=72
x=12

Answer:

First we have to find the value of x;

then we have to find the value of y;

Step-by-step explanation:

here,

2x= 12

x = 12\2

x = 6

now,

4y = 12

y = 12\4

y = 3

We can see here that there are 2 triangular bases on the prism.

To calculate the area of a triangle, we multiply the base and the height and then divide by 2.

A = 8 x 6 /2

A = 48/2

A = 24

Hope it helps!
