Answer:
Step-by-step explanation:
By interior angle property on one side of the transversal.

Answer:
120 cm squared
Step-by-step explanation:

Answer:
15.78°
Step-by-step explanation:
Let the angle be x.
From the x, the known sides are the opposite side, O(13) and the adjacent side, A(46)
Therefore, The trigonometric ratio is the tangent ratio.
tan x = O/A
tan x =13/46
x = 15.78°
B is true because 0-(-x) = 0 + x = x
Answer:
r = 8
Step-by-step explanation:
The common ratio r of a geometric sequence is
r =
=
= ..... = 
Then
r =
=
= 8
