13
Step-by-step explanation:
There is the largest quantity of '13' in the list of data. Hence, 13 is the mode of the list of the data.
Pythagorean theorem
c2 = a2 + b2
58^2 = 42^2 + b2
3364 = 1764 + b2
1600 = b2
b = 40
Answer:
54 sq units
Step-by-step explanation:
The triangle at the top (FAB) has a base of 10 and a height of 3. Area of triangle is 1/2bh so 1/2(10 * 3) = 1/2 * 30 = 15 sq units
If you cut off the triangle you have a trapezoid, EBCD. A trapezoid is (b1 + b2)/2 * h, so (6 + 7)/2 * 6 = 13/2 * 6 = 6.5 * 6 = 39 sq units
Add them together: 15 + 39 = 54 sq units
