Answer:
x = 31.5° and z = 63°
Step-by-step explanation:
Given:
Line AB intersects line AB
Given angle = 117°
Now a linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines.
hence we can say,
Also,
Hence x = 31.5° and z = 63°
Answer:
40.0 mL
Explanation:
The volume of a substance when given the density and mass can be found by using the formula:
Volume = mass/density
From the question:
mass = 420 g
density = 10.5 g/cm³
The volume is:
Volume = 420/10.5
We have the final answer as
40.0 mL
