In ΔRST, the measure of ∠T=90°, ST = 7.7 feet, and RS = 9.7 feet. Find the measure of ∠R to the nearest degree.

Match each inequality to the number line that represents its solution

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?
