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
Answer:
42
Step-by-step explanation:
Since the scale factor is , we know that the bigger shape went to the smaller shape.
If we know that the smaller shape's side, 12, is of the bigger one, we can make the equation
.
To solve for x, we can divide both sides by .
We can multiply by the reciprocal:
