Angles a, b, and c are all 60°. A triangle’s angles add up to 180, and if the triangle is equilateral, each angle must be 60 (180/3). Angle d is 120° because b and d form a supplementary angle (180°), so 180-60 is 120. Angle e and f and 30°. Angles c and e form complementary angles (90°), so 90-60=30. For f, if the triangle adds up to 180, 180-120-30 = f. The 120 comes from d and the 30 comes from e. This leaves f as 30.
32% = 0.32
Usually = 400x32/10
Now do 32/100 = .32
Answer is A. 400x0.32
Answer:
To solve this you must first know how Log works.
When we say log1000 of base 10
Or
log1000=3
What we actually say is for the power 3(value on RHS) of 10(the base of log) we get 1000(the value on which log is performed).
So log2x=−5 (i am assuming base 10 since it is simple algebra) means that
2x=10−5
x=10−5/2
Do this simple calculation and you have it. If anything is unclear/incorrect feel free to comment.
The question is not written properly, so I will give the answer(s) I think would be suitable.
If you were trying to solve this
log2x=−5
⟹x=2−5
⟹x=132
But if you were trying to solve this
log2x=−5
⟹log102x=−5
⟹2x=10−5
⟹x=12×105=1200000
