Answer:
Here's one way to do it
Step-by-step explanation:
Divide the hexagon into triangles, for example, as in the diagram below.
The triangles are all inside the hexagon, so the sum of their interior angles is the sum of those of the hexagon.
The sum of the interior angles of a triangle is 180°.
There are four triangles, so
Sum of interior angles = 4 × 180° = 720°
Answer:
r = 54 miles per hour
Step-by-step explanation:
Since we have been given the values for two of the unknowns, we can substitute them into the equation to find the third.
d = 405
t = 7.5
d = rt
405 = r (7.5)
405=7.5r
Now to find r, we need to get it by itself on one side so we have r = ...
We can do this by dividing 7.5 from both sides of the equation as this will cancel out the 7.5, leaving us with the r value, and everything you do to one side of an equation must also be done to the other side.
405/7.5=7.5r/7.5
54=r
The unknown value 'r' = 54
Since 'r' stands for 'rate', the units given must be appropriate for speed. As the distance was given in miles, and the time in hours, the unit for 'r' must be miles/hour. Therefore r=54miles/hour.
Hope this helped!
Complementary is when angles equal 90 degrees.
supplementary is when angles equal 180 degrees.
a)
supp:145 degrees
comp:55 degrees
b)
supp:23 degrees
comp: none
c)
supp:159 degrees
comp:69 degrees
Answer:
Step-by-step explanation:
h(t)=-16t²+32t+64
=-16(t²-2t)+64
=-16(t²-2t+1-1)+64
=-16(t-1)²+16+64
=-16(t-1)²+80
maximum value=80 and is obtained at t=1
