Answer:
51 ft²
Step-by-step explanation:
The shaded area is the area of the triangle subtract the area of the rectangle.
The area (A) of the triangle is calculated as
A =
bh ( b is the base and h the perpendicular height )
Here b = 11 and h = 10, thus
A = 0.5 × 10 × 11 = 5 × 11 = 55 ft²
Area of rectangle = 1 × 4 = 4 ft², hence
Area of shaded region = 55 - 4 = 51 ft²
Isosceles triangle
so
x + 8 = 2x -1
x = 9
BC = 3x - 3
BC = 3(9) - 3
BC = 27 - 3
BC = 24
Answer:

Step-by-step explanation:
a reciprocal is a number that when multiplied by a given number gives 1 as product.
16 * x = 1
x = 1/16
9/10 * x = 1
x = 10/9
