Answer:
∠ AOB = 139°
Step-by-step explanation:
Since AOC is a straight line then
∠ AOB + ∠BOC = 180° , that is
8x + 51 + 6x - 25 = 180
14x + 26 = 180 ( subtract 26 from both sides )
14x = 154 ( divide both sides by 14 )
x = 11
Then
∠ AOB = 8x + 51 = 8(11) + 51 = 88 + 51 = 139°
The units digit of the given exponential expression will be 6
<h3>Determining the units digit of an exponential expression</h3>
From the question, we are to determine the units digit of the given exponential expression
The given exponential expression is
4⁸⁰⁰
We know that
4¹ = 4
4² = 16
4³ = 64
4⁴ = 256
4⁵ = 1024
4⁶ = 4096
From above, we can observe that the units digit of the odd exponents is 4 while the units digit of the even exponents is 6.
The exponent of the given expression is 800. 800 is an even number.
Hence, the units digit of the given exponential expression will be 6
