20pts. Find the measure of ∠BEC. A) 10° B) 60° C) 80° D) 100°
Schach [20]
<h2>Explanation:</h2><h2></h2>

The figure to this problem is attached below. We know that angles ∠AEG and ∠GEC are supplementary, so:

∠AEG + ∠GEC = 180°

∠AEG = 8x°

∠GEC = (4x + 60)°

8x° + (4x + 60)° = 180°

(12x + 60)° = 180°

12x + 60 = 180

12x = 180 - 60

12x = 120

x = 10

∠AEG and ∠BEC are vertical angles, so they are congruent:

∠BEC = 8x°

∠BEC = 8(10)°

∠BEC = 80°

Explain the step(s) needed to solve 4+ p = 1 and then solve for p
liberstina [14]

Answer:

p = -3

Step-by-step explanation:

Apply algebra to the equation by subtracting 4 from each side, that way it will cancel out at least the 4 next to p. It should now look like this: p = -3

Because we can't make anymore moves and the expression clearly states what p is, we're done!
