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)
I guess just work backwards.
x=-3
2x=-6
x=-x-6
There ya go :P
Answer:
d
Step-by-step explanation:
A segment joining the midpoints of a triangle is
• Parallel to the third side
• Half the length of the third side
The segment DF joins the midpoints of 2 sides of Δ ABC , then
BC = 2 × DF = 2 × 4 = 8
