Solve for x: −4|x + 5| = −16
Annette [7]
-4 | x + 5 | = -16...divide both sides by -4, eliminating it on the left side
| x + 5 | = -16/-4
| x + 5 | = 4

x + 5 = 4           -(x + 5) = 4
x = 4 - 5            -x - 5 = 4
x = -1                 -x = 4 + 5
                          -x = 9
                           x = -9

solutions : x = -1 , x = -9

13. Find the measure of ZABC. Show your work.<br>​
ale4655 [162]

Answer:

47°

Step-by-step explanation:

In the picture attached, the problem is shown.

When two secants intersect at a point, the angle made is one-half of the difference between the greater arc and the minor arc formed. In this case:

∠ABC = 1/2*(arc DE - arc AC)

Replacing with data from the picture:

∠ABC = 1/2*(142° - 48°)

∠ABC = 47°
