Step-by-step explanation:
You have this rule, if there is < 30° then value of y is
y=12✓3:2
y=6√3
And Pitagora's theorem:
c²=a²+b²
In this case:
(12√3)²=y²+x²
Then x is:
x²= (12√3)²-y²
x²= (12√3)²-(6√3)²
x²=432- 108
x²= 324
x=✓324
x=18cm
The answer to your problem is 54.
Step-by-step explanation:
(x-3y=7)2
2x-6y=14
- 2x-6y=12
__________
-12y=2
y=-1/6

Maybe use a ruler To find the area and add them together to fin the volume.
