The answer would be 32 degrees
You will have to make the fraction a decimal first by dividing the top number by the bottom number then divide if your other number is already a decimal/whole number
Since multiplying by 0.5 is the same as dividing by 2, the problem is described by the sentence
"Half the sum of a number and 40 equals 200"
The correct answer is B) AC = BC
We know this because the two triangles are equal due to SAS
Percentage Change = (New - old ) / (old) *100
85 - 74 = 11
11 / 74= 0.1486 * 100 = 14.8648.
To the nearest hundredth = 14.86 %
