The answer is 12 feet because 144 squared is 12.
Hope this helps
<h3>We know that :</h3>
<h3>Asked :</h3>
A = …?
<h3>Solution :</h3>
A = ½ (a + b) × h
A = ½ (6 + 2) × 3
A = ½ (8) × 3
A = 4 × 3
A = <u>12</u> square units.
Answer:
C. The triangles are not similar
Step-by-step explanation:
For two triangles to be considered similar, the 3 angles of one triangle must be equal or congruent to the corresponding 3 angles of the others.
The only angle in ∆BCG that is equal to the corresponding angles in ∆EFG is <BGC. The remaining 2 angles in ∆BCG are not congruent to the corresponding 2 angles in ∆EFG.
Therefore, we can conclude that both triangles are not similar.
Answer:
The center is located at (-1, -2), and the radius is 5.
Step-by-step explanation:
The general equation of a circle is given as
(x - a)^2 + (y - b)^2 = r^2
where
a and b are the centre of the circle and r is the radius
Given the equation
x2 + 2x + y2 + 4y = 20
add 1 ad 4 to both sides
x2 + 2x + 1 + y2 + 4y + 4 = 20 + 4 + 1
factorise
(x +1)^2 + (y+2)^2 = 5^2
comparing with the general equation
a = -1, b = -2, r = 5 (all measured in units)
