Since it's a square, the sides are all the same. This is going to be the equation.
S²=196
14×14=196
The length of one side is 14.
A rational number is a number that can be written into a fraction. pi, some square roots, e, etc., are irrational numbers(numbers that cannot be written into a fraction).
To find the measure of angle a, subtract 151 from 180. (Reason: line w equals 180º, and the second angle is the same size as the 151º angle.)
180 - 151 = 29
<h2>Answer:</h2>
<u>Angle a = </u><u>29º</u>
