Which equation is correct regarding the measure of 21?
OmZ1 =
1 = {(a-c)
O m_1 = {(a + c)
O m_1 = {(6-0)
= {(b + c)
Om21 =

answer is (b.

164 ft2)

a base  

18

b base  

7

h height  

8

the answer is that it is true

answer: math isn’t just mysterious because the majority of us find it so difficult to understand – it’s also the basis of the universe, giving us clues to physical phenomena like the motion of gases in the atmosphere and the way that physical particles interact with each other amid all the possible variables in three-dimensional space.
