x=5
Answer:
<B is 126degrees
Step-by-step explanation:
Find the diagram attached. From the diagram, <A = <B (corresponding angle)
Given
<A = 8x + 78
<B = 2x+114
Equating both expressions
8x+78 =2x + 114
8x-2x = 114 - 78
6x = 36
x = 36/6
x = 6
Get <B
Recall that <B = 2x+114
<B = 2(6) + 114
<B = 12 +114
<B = 126degrees
Hence the measure of <B is 126degrees
Answer:
The 8th term of the sequence is 255
Step-by-step explanation:
To find the 8th term of the sequence, we have to use the given sequence formula
All we have to do here is to make a substitution
We simply have to substitute the value 8 for n as follows;
a8 = 2^8 - 1
a8 =256-1
a8 = 255
