If two angles are complementary, it means that they add up to 90 degrees.
It two angles are congruent, it means that they have the same angle measure.
Let the angle measure of AXB = x
and the angle measure of BXC = y
Because the two angles are complementary i.e. they add to 90:
x + y = 90
Because the two angles are congruent i.e. they equal each other:
x = y
Plug x = y back into the first equation.
x + x = 90
x = 45
y = 45
Angles AXB and BXC are both 45 degrees.
This equals 19.872.
If you multiply 7.2 by 12 and 0.23 then you would get 19.872 then to round it to the nearest hundredth it would be 19.902 because 7 is a greater number than 5 so that would make the 8 into a 9 and then 7 into a 0 and then you would keep the 19 and the 2
hexagon
Edges and vertices: 6
if you cut it up it could be four triangles!
Did this help you luv!? c:
That's only one term.
' 10 + x ' would be two terms.
