Using the equations for tangent and secant lines:
Let the unknown length of the line inside the circle = y
6^2 = 3 x (y+3)
Simplify:
36 = 3y+9
Subtract 9 from both sides:
27 =3y
Divide both sides by 3:
Y = 9
Now add to get x:
X = 9 + 3 = 12
X = 12
When you solve the following equation, solving for the quadratic formula.
The answer is; x=4

Answer:
1 1/3
Step-by-step explanation:
2/5 x 10/3
<em>Multiply across - </em>
10 x 2 = 20
5 x 3 = 15
20/15
<em>Simplify - </em>
20/15 to 4/3
Divide 4 by 3
You get 1 1/3

Answer:
the lateral area of the regular prism is 30 cm².
Step-by-step explanation:
Given;
the base of the regular prism, b 4cm
height of the prism, h = 2.5 cm
The lateral area of the regular prism is calculated as the product of the base perimeter and height of the prism.
L.A = P x h
where;
P is the perimeter of the base = 3 x 4cm (equilateral triangle has equal sides)
P = 12 cm
L.A = 12 cm x 2.5 cm
L.A = 30 cm²
Therefore, the lateral area of the regular prism is 30 cm².
