10+21+25.
the area is 56 inches.
so what i did was take the number 21 (the area of the rectangle) and figure out which two reasonable numbers multiply to make up that number. and then the green box is a square so that leads me to believe it’s a 5x5. and the other box is 5x2 = 10.
138 Degrees because it’s supplementary so 180 - 42 = 138
Any irrational number when added to 0.4 produce an irrational sum.
Example: #0.4+pi# is irrational
(H)ypotenuse (L)eg, right-triangle theorem.
based on the provided graph, we know the hypotenuses are equal, thus the tickmarks, so H is true, now the L part, we only need either of the pair of legs to be equal DM = NB or AM = CN, if either one is true, we're golden.
The formula for a regular polygon, which this one is, is A = 1/2 ap where a is the apothem and p is the perimeter. 20.8 * 7 = 145.6 which is the perimeter, so now just multiply by 21.6 and .5. 145.6 * 21.6 * .5 = 1572.48, or B above.
