John is constructing a triangle with two sides 5cm and 7 cm and the included angle is 70°. First, John draws a 5cm segment on his paper. He is not sure how to construct the 70° angle. What should he do? A) Using a compass, draw a 7 cm circle. B) Since 70° is less than 90°, just make sure to draw an acute angle. C) Using a straightedge, measure a 7 cm segment from an endpoint of the 5 cm segment. D) Using a protractor, measure a 70° angle from the endpoint of the 5 cm segment.
