Answer:
x=40 °
Step-by-step explanation:
The two horizontal beams are parallel and the slanted beams make a traversal
Hence we use the basic properties of a transverse line making with two parallel lines.
please refer to the image attached to this answer.
The two angles described in the figure makes the alternate interior angles and this these two are congruent . Hence
x= 40°
Answer:
The common difference (or common ratio) = 0.75
Step-by-step explanation:
i) let the first term be = 80
ii) let the second term be =
. r = 80 × r = 60 ∴ r =
= 0.75
iii) let the third term be =
. r = 60 × r = 45 ∴ r =
= 0.75
iv) let the fourth term be =
. r = 45 × r = 33.75 ∴ r =
= 0.75
Therefore we can see that the series of numbers are part of a geometric progression and the first term is 80 and the common ratio = 0.75.
