Using herons formula you find the area
s=24/2=12
A=24
and A=0.5 base height
sp
24=0.5 (base=AB=10)(height=c to the midpoint of segment AB)
24=5(height)
=height
Answer:
be smart you will knoow thanks for the free ppints hahaha
Step-by-step explanation:
Answer:
The exponent 0 makes the number as 1.
the sum of the angles in an ngon (a polygon with n sides) is (n-2)*180
so an octagon has 8 sides and has a sum total of (8-2)*180=1080 degrees
if each of 7 angles is 132, then 1080=?+7*132
1080=?+924
156=?
the 8th angle is 156 degrees
K = 19. When you follow order of operations you start with Parenthesis.
So, plug in 19 first. (19+3) = 22 and (19+1)=20.
From there, you multiply the number outside the parenthesis.
22 * 4 = 88 + 2 = 90
Do the math on the other side now.
20 x 4.5 = 90
Considering they both equal 90, your problem is complete, and your answer for K is 19.
I hope this helps (:
