Answer:
-12.5% error
Step-by-step explanation:
Step 1. Subtract the actual value (40) from the estimated value (35)
35-40 = -5
Step 2. Divide the results (-5) with the actual value (40)
-5/40=-0.125
Step 3. Find the percent by multiplying the result (-0.125) by 100
-0.125 * 100 = -12.5
Therefore, the percent error was -12.5%
Answer:
m<BAC= 110 degrees
Step-by-step explanation:
Since the outside angle m<BCD is 130 degrees the inside angle m<BCA would be 50 degrees. At this point you should know that inside angles of a triangle add up to 180 degrees so add the two angles that you know then subtract from 180 degrees. 50+20= 70 degrees and 180-70= 110 degrees.

Answer:
2.161 to the nearest thousandth.
Step-by-step explanation:

By the definition of a logarithm:
20 = 4^x
ln 20 = x ln 4
x = ln20 / ln 4
x = 2.161 to the nearest thousandth.
