Answer:

A=15

Step-by-step explanation:

This is a 3, 4, 5 triangle, so the perimeter of the triangle is a+4x+5x. You know that the x's go from 4x--20 and 5x--25. X=5, and 5x3=15

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°
