The perpendicular line would have a slope of A) -3/2.
Perpendicular lines have opposite and reciprocal slopes.
To do the opposite, take the original slope (2/3) and change the sign (-2/3).
To do the reciprocal, take the slope we changed (-2/3) and flip it as a fraction (-3/2).
This gives us a new slope of -3/2.
Answer:
a = 9.4 cm
b = 12.0 cm
Step-by-step explanation:
Check the image uploaded for diagram;
For the first diagram, side length a is calculated as follows;
a² = 8² + 5²
a² = 64 + 25
a² = 89
a = √89
a = 9.4 cm ( approximated to 1 decimal place)
For the second diagram, side length b is calculated as follows;
b² = 17² - 12²
b² = 145
b = √145
b = 12.0 cm (approximated to 1 decimal place)
