Answer:

x=4

Step-by-step explanation:

Midpoint Theorem: The line joining the midpoints of two sides of the triangle is half of the length of the third side and parallel to it.

From the given figure we can see that BE is the line segment joining midpoints of two sides of the triangle. This means that

BE=\frac{1}{2} CD        [ By midpoint theorem]

Substituting values of the lengths of BE and CD

x+2=\frac{1}{2}\times 12

Simplifying and solving for x.

x+2=6

Subtracting both sides by 2

x+2-2=6-2

x=4

∴ x=4

Harrizon [31]

Answer:

Temperature after 12 hours = 25°C

Step-by-step explanation:

Given:

Current tempreture = -23°C

Tempreture incresing rate = 4°C per hour

Total time = 12 hour

Find:

Temperature after 12 hours

Computation:

Temperature after 12 hours = Current tempreture + (Tempreture incresing rate)(Total time)

Temperature after 12 hours = -23 + (4)(12)

Temperature after 12 hours = -23 + 48

Temperature after 12 hours = 25°C
