Answer:
64 + 64sqrt(3)
174.9 cm²
Step-by-step explanation:
AD/2 = 8cos(60) = 4
AD = 8 cm
Height of each triangle = 8sin(60)
= 4sqrt(3)
sqrt: square root
Area = 8² + 4(½ × 8 × 4sqrt(3))
= 64 + 64sqrt(3) cm²
= 174.8512517 cm²
Answer:
true
Step-by-step explanation:
Considering we have a line segment for (0,0) to (0,8).
The midpoint is (0,4).
The formule for calculate the distance between two points is:
We substituye the values:
= 8
The point halfway between the endpoints is (0,4)
that is the half of the distance between the points.
The answer is b hope this helps
Answer:
x^2 +4x = 18
Step-by-step explanation:
The variable y is isolated in the first equation by dividing both sides by the coefficient of y:
3y = 12x . . . . . . given
3y/3 = 12x/3 . . . . . divide by the coefficient of y
y = 4x . . . . . . . simplify
__
This expression (4x) is put in place of y when substitution is used.
x^2 +y = 18 . . . . given
x^2 +4x = 18 . . . . . with 4x substituted for y
