Answer & Step-by-step explanation:

In order to solve this problem, it  is important that we know the original form of this equation.

<em>(x - x1)² + (y - y1)² = r²</em>

The equation we are given is: <em>(x - 1)² + (y + 20)² = 196</em>

Now that we know the original equation and the given equation, then we can conclude that the center of the circle is (1, -20). We can find the radius by calculating the square root of 196.

√196 = 14

So, the radius is 14.

Now, based on the given information, we know that the center of the circle is (1, -20) and the radius of the circle is 14.

Find the area of the triangle.
Vsevolod [243]

Answer:

20 m²

Step-by-step explanation:

<u>Formula (Area of triangle):</u>

<u />\text{A (Triangle)} = \dfrac{1}{2}  \times \text{Base} \times \text{Height}

From the triangle, we can see that the base of the triangle is "7 + 3" m and the height of the triangle is "4" m.

<u />\implies \text{A (Triangle)} = \dfrac{1}{2}  \times (7 + 3) \times (4)

Simplify the right-hand-side as needed to evaluate the area.

<u />\implies \text{A (Triangle)} = \dfrac{1}{2}  \times (10) \times (4)

<u />\implies \text{A (Triangle)} = \dfrac{40}{2}  = 20 \ \text{m}^{2}

Therefore, the area of the provided triangle is 20 m².
