E To determine the length of the unmeasured side, divide the figure into a rectangle with length 65 and a right triangle. If the height of the triangle is 40 and the hypotenuse is 50, then by the Pythagorean theorem the other leg is 30; the top segment of the rectangle is 65 like ...

The ph in “phishing” comes from the mid-1900s hobby of “phone phreaking,” in which enthusiast “phreaks” would experiment with telecommunications networks to figure out how they worked. Phreaking + fishing = phishing. Spam vs. phishing The key difference between spam and phishing is ...
An exterior angle of a triangle equals the sum of thetwo remote interior angles. Set up an equation and solvefor x:7x=4x+603x=60x=20So the angle marked 7x^(° ) has a degree measure of 7(20)=140 The angle marked a^(° ) is supplementary tothis angle, so its measure is 180...

There's no way to figure out the area of the shaded region directly, but you can figure out the area of the non-shaped region and subtract. Since the radius of the circle is 5, you know that the area of the circle is 25π. Subtract that from the area of the square, 100, to ge...
