Answer:

x = 9

Step-by-step explanation:

Given a segment joining the midpoints of 2 sides of a triangle, then

the segment is half the length of the 3rd side , that is

3x = 0.5 × 54 = 27 ( divide both sides by 3 )

x = 9

Answer:

D. $70.34 cm^2$

Step-by-step explanation:

Area of sector of a circle is given as θ/360*πr²

Where,

r = radius = 12 cm

θ = 56°

Use 3.14 as π

Plug in the values into the formula and solve

$area = \frac{56}{360}*3.14*12^2$

$area = 70.34$

Area of the sector ABC = $70.34 cm^2$

The answer is D

Answer:

B. 18

Step-by-step explanation:

$x^{2} + 36x + 324 = (x + m)^{2}$

$(x+18)^{2}= (x + m)^{2}$

$\cancel x+18= \cancel x + m$

$18= m$
