Answer:

A = 70

Step-by-step explanation:

CB is equal to EZ and E equals 35, and E and C are the same, therefore, both E equals 35. Since there's 180 degrees in a triangle, and ABY equals 105, you have to subtract 180 - 105 to get the other angle. When you do that, you get that B equals 75. You have to add E and B (35 + 75), since that's in the same triangle as A. When you do that, you get 110. Subtract 180 - 110 to get A, which is 70.

<h3>The absolute error is 6</h3><h3>The percent error is 16.22 %</h3>

Solution:

Given that,

Actual volume of his bathtub is 37 gal

Estimate is 31 gal

Find the absolute error

Absolute Error = | Measured Value - Actual Value |

Absolute Error = | 31 - 37 |

Absolute Error = 6

Find the percent error

$Percent\ error = \frac{\text{estimate - actual}}{actual} \times 100$

Substituting we get,

$percent\ error = \frac{31-37}{37} \times 100\\\\percent\ error = \frac{-6}{37} \times 100\\\\percent\ error = -16.22$

Negative sign means percent decrease

Thus percent error is 16.22 %
