The answer is 51°.
The top two lines are parallel to each other. Therefore alternate interior angles theorem applies. The bottom right corner that is underneath the line (for lack of a better description) is also 58°.
We also know that a triangle equals 180°. So 58+71= 129°.
So to find that missing angle we subtract 129 from 180 to get the 51°.
5x+x=90 degree
x=90\6
x=15
5x=15*5=75
75+15=90degree
Answer:
92 92 238
Step-by-step explanation: 92 because a proton and electron have the same and first is 92 and well 238

Hello from MrBillDoesMath!
Answer:
Choice E.
Discussion:
Assuming that n >=1, a(n) = 4n -1, then
a(10) = 4(10) - 1 = 39
but that doesn't match any of the answers...... hmm...
BUT
If you meant that a(n) = 4^(n-1), then
a(10) = 4^(10-1) = 4^9 = 262144
which is Choice E.
Thank you,
MrB
