B)8 good luck on the assignment
Answer:
1.06666666667. this could be wrong as I got this of Google. or 1.06 . btw idk how to explain it
Answer: x = 3.Explanation:The expression is miswritten.
I am going to try to show it correctly writen using the math editor:
Just to be sure that it is understandable, the expression is read: logarithm base (4x - 10) of 32 equals 5.
To solve it, you take antilogarithm:
[4x - 10]^5 = 32
Now decompose 32 in 2^5
=> [4x - 10]^5 = 2^5
=> 4x - 10 = 2
=> 4x = 12
=> x = 12 / 4 = 3
Answer: x = 3
Angle BOC = 65°
Angle AOC =90° ( ∵ it is right angle )
The measure of angle AOB .
Since it is right-angle,
+ 65° = 90°
= 90° - 65°
= 25°
➡ ∠ AOB + ∠ BOC = ∠ AOC
➡ 25° + 65° = 90°
➡ 90° = 90°
➡ L. H. S. = R. H. S
Hence verified. ✔
