Plz me with geometry !
the picture below shows a portion of a river dam: a right angle triangle is shown with acute angle on base equal to 50 degrees and the length of base equal to 115 meters. which of the following can be used to calculate the height of the river dam?

City l has a temperature of −3 °f. city m has a temperature of −7 °f. use the number line shown to answer the questions: number line from negative 8 to positive 8 in increments of 1 is shown. part a: write an inequality to compare the temperatures of the two cities. (3 points) part b: explain what the inequality means in relation to the positions of these numbers on the number line. (4 points) part c: use the number line to explain which city is warmer. (3 points)
