Answer:
x = -2
∠A = 35
Step-by-step explanation:
x + 37 + x + 57 = 90
reduce:
2x = -4
x = -2
∠A = 37-2 = 35
Step-by-step explanation:
EF is a segment so it's a line with the end points as E and F. Line RS bisects(cuts in half) line EF. Then where the two lines meet is where A is.
Hope this helped.
A "derivative" is a rate of change.
The derivative of a plain old number is zero, since numbers never change.
Pi is a number. Its value never changes. Its derivative is zero.
To find the percent of anything, you divide what you have from the total (or the smaller number over the bigger number). In this case, you will do 14/26.
14/26=0.53846
I'm going to round to the hundredths: 0.54
Move the decimal place two times to the right: 54
The percent change from 14 inches to 26 inches is 54%
