Which of the following statements describe how to find the measure of EC? Right triangle ADC with segment BE creating right triangle BEC where A and B are the right angles. AD is 4 times the square root of one hundred thirty-eight miles, BE is the square root of one hundred thirty-eight miles, and AB is six times the square root of three miles. Which of the following statements describe how to find the measure of EC? Segments AD and BE are similar to segments AC and BC. Create a proportion to find segment BC and then apply the Pythagorean Theorem to find segment EC in triangle BEC. Triangles ADC and BEC are similar. Create a proportion with the legs to find the length of segment BC. Then use the Pythagorean Theorem to find segment EC. Segments AB and BC are congruent. Apply the Pythagorean Theorem to triangle BEC to find segment EC. Create a proportion with the legs of the triangles where segment BC is the same measure as segment AB. Add the length of segments BC and BE to find the length of segment EC.
