Let's look at the decimal number. We want to know where root 91 is in relation to the decimal number. The decimal number is between 12 and 13, or in other words, between
and
. Both of these numbers are larger than
meaning that the answer has to be
A
2. X=3
Explanation: You do the opposite of the number. Its a -3 which means subtract 3 so add 3.
6. X=15
Explanation: You do the same for 2 so do the opposite which would be 15.
So basically, its a theorem.
Angle U = half of 288
Angle U = 144
Angle U and Angle VUT are supplementary, which means the sum of their measure is 180 so,
144 + 8x + 4 = 180
Now solve for x
x = 4
tolerance in ohms
4500 * 3/100 = +/- 135 ohms
the actual range is 4365 to 4635 ohms
