Answer:
x=7
Step-by-step explanation:
by pythagoras, 25^2=24^2+x^2
solve for x
Answer: x = 63
Step-by-step explanation:
15/3 = 5
3 * 21 = 63
63/15 = 21/5
Answer: The decimal is 0.583
Step-by-step explanation:
Parallel slope = 2
This is because the original line has slope 2. Parallel lines have equal slopes.
--------------------------
Perpendicular slope = -1/2
The original slope 2 or 2/1 turns into -1/2 after flipping the fraction and the sign. Note the original slope and perpendicular slope multiply to -1. This is true for any pair of perpendicular lines where neither line is vertical.
the answer is 2.7. 5.0 - 2.3 = 2.7
