Answer:
Use the pythagorean theorem to solve.
Step-by-step explanation:

The square root and the square cancel out. Then your answer will be the square root of 13 or 3.60555127546. Since the instructions say to round to 2 places we will do so. 3.61 meters is the length of the slide
Step-by-step explanation:

here 8x and (2x+60) are corresponding angles
since line l1 and l2 are parallel, so the two angles will be equal
8x=2x+60
8x-2x=60
6x=60
dividing by 6
x=10
option D. 10 is correct
m = −3/4 is the correct answer. Hope this helps!
