Answer:

Step-by-step explanation:

you know the total angle is 180° from A to D

and you know that ∠BEC is 90°

also you are told that ∠CED is 18°

and that ∠AEB is 4x°

so just put that all together

180=90 + 18 +4x

now solve for X

180-90-18=4x

72=4x

18 = x

so now you know X

now solve ∠AEB

4(18) = 72°

∠AEB= 72°

Which number line shows the solution 1/2x-2>0

Ymorist [56]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$\frac{1}{2}x-2>0$

Solve for x

$\frac{1}{2}x>2$

$x>4$

The solution is the interval ------> (4,∞)

All real numbers greater than 4

In a number line, the solution is the shaded area at right of x=4 (open circle, the number 4 is not included in the solution)
