14 is always 15 is sometimes 16 is sometimes
Answer:
x = -3
Step-by-step explanation:
-12 = 6x + 6
Start by subtracting 6 from both sides to get the 6x alone on the right.
-18 = 6x
Divide both sides by 6 to find out what x equals
x = -3
-1,3 that’s easy u should definitely pay attention in class
The measure of angle CDE ( ∠CDE) is 55°. The correct option is the first option 55°
<h3>Calculating the measure of the angle formed by two tangents</h3>
From the question, we are to determine the measure of angle CDE.
From one of the circle theorems, we have that
"<em>The measure of the angle formed by two tangents that intersect at a point outside a circle is equal to one-half the positive difference of the measures of the intercepted arcs</em>"
Thus,
m ∠CDE = 1/2(measure of arc CBE - measure of arc CE)
From the given information,
Measure of arc CE = 125°
Then,
Measure of arc CBE = 360° - 125°
Measure of arc CBE = 235°
Therefore,
m ∠CDE = 1/2(235° - 125°)
m ∠CDE = 1/2(110°)
m ∠CDE = 55°
Hence, the measure of ∠CDE is 55°
