Answer:
20
Step-by-step explanation:
one way is guess and check method, you draw a table and try out 3 different consecutive even numbers to see which 3 add up to 66
We know that
tan ∅=opposite side angle ∅/adjacent side angle ∅
adjacent side angle ∅=opposite side angle/tan ∅
in this problem
see the attached figure to better understand the problemangle ∅=80°
opposite side angle ∅=12 ft (AB)
adjacent side angle ∅=? (AC)
adjacent side angle ∅=12/tan 80°------> 2.12 ft
the answer is2.12 ft
Answer:
Step-by-step explanation:
Given that:
Difference of two trinomials is
One of the two trinomials is
To find:
The other trinomial = ?
Four options are:
Solution:
Let the two trinomials be A and B.
Given A - B =
B =
We have to find the other trinomial A.
A - B =
A - () =
A = + ()
A =
So, the correct answer is .
