Answer:
r = 2
Step-by-step explanation:
The first differences between successive terms are ...
10 -5 = 5
20 -10 = 10
The differences are not constant, so the sequence is NOT arithmetic.
__
The ratios of successive terms are ...
10/5 = 2
20/10 = 2
The ratios are constant, so the sequence is ...
geometric with a common ratio of 2.
I believe it's A but it's not exactly clear

Step-by-step explanation:
17 - 5 = 12 divided by 4 = 3
A. 63.1°
<u>Step-by-step explanation:</u>
Whatever it may be reflection, rotation or translation, the angle or size of the triangle will not change.
As we know that the sum of angles in a triangle is 180°.
In ΔX'Y'Z', ∠X' + ∠Y' + ∠Z' = 180°
53.8° + 63.1° + ∠Z' = 180°
116.9° + ∠Z' = 180°
∠Z'= 180° - 116.9°
= 63.1°
