Answer:
Explanation:
Given the coordinates of the triangle as:
B(2, -8), C(-6, -2), and D(-7, -5)
The area is obtained using the formula:
Using the given parameters, we have:
Answer:
Step-by-step explanation:
Let's solve (4y - 3)^2 = 72 for y. To do this, take the square root of both sides. This yields:
4y - 3 = ±√72 = ±√(36·2) = ±6√2
Then 4y = 3 ±6√2, or
3 ± 6√2
y = ----------------
