PLS HELP I WILL MARK BRAINLIEST TO CORRECT AND EXPLAIN ANSWERS!!!!!!!!!!!!!!!!!!!(Two Questions)Which relationship is always true for the angles r, x, y, and z of triangle ABC? (first picture) x + z = y 180 degrees − x = r x + y + z = 180 degrees x + y + z = 90 degreesThe figure shows two parallel lines AB and DE cut by the transversals AE and BD: (second picture)Which statement best explains the relationship between Triangle ABC and Triangle EDC ? Triangle ABC is similar to triangle EDC , because m∠3 = m∠6 and m∠1 = m∠4 Triangle ABC is similar to triangle EDC , because m∠3 = m∠4 and m∠1 = m∠5 Triangle ABC is congruent to triangle EDC , because m∠3 = m∠4 and m∠1 = m∠5 Triangle ABC is congruent to triangle EDC, because m∠3 = m∠6 and m∠61 = m∠4

Described below are the first three steps for constructing the perpendicular bisector of a line segment. 1. Start with a line PQ. 2. Place the compasses on one end of the line segment. 3. Set the compasses' width and draw an arc above and below the line. Which BEST describes the width required in step 3? A) slightly shorter than one-quarter the length of the line segment B) slightly lomger than one-quarter the length of the line segment C) slightly shorter than one-half the length of the line segment D) slightly longer than one-half the length of the line segment

10 points i guess Look at the picture of a scaffold used to support construction workers. The height of the scaffold can be changed by adjusting two slanting rods, one of which, labeled PR, is shown:Part A: What is the approximate length of rod PR? Round your answer to the nearest hundredth. Explain how you found your answer, stating the theorem you used. Show all your work. (5 points)Part B: The length of rod PR is adjusted to 16 feet. If width PQ remains the same, what is the approximate new height QR of the scaffold? Round your answer to the nearest hundredth. Show all your work. (5 points)
