Answer:
135°+97°+x=180°. 232°+x=180°. x=232-180=102°
:x=102°
Answer:
a₆ = 6
Step-by-step explanation:
There is a common ratio r between consecutive terms in the sequence, that is
r =
=
=
= - 
This indicates the sequence is geometric.
To obtain any term in the sequence, multiply the previous term by r, thus
a₅ = 216 × -
= - 36
a₆ = - 36 × -
= 6
Answer:

Step-by-step explanation:
Use FOIL:
<em>(a + b)(c + d) = ac + ad + bc + bd</em>
We have:

<em>combine like terms</em>
