Answer:
Step-by-step explanation:
hello :
cos²θ +sin²θ = 1 and cosθ =4/5
(4/5)² + sin²θ = 1 so : sin²θ = 1 - 16/25
sin²θ = 9/25 = (3/5)²
sinθ = 3/5 or sinθ = - 3/5 because : (3/5)²= (- 3/5)²= 9/25
The area of the L shaped figure is 258 ft²
<h3>
Area</h3>
Area is the amount of space occupied by a two dimensional figure.
The area of a rectangle is given by:
Area = length * breadth
From the diagram, the area is:
Area = [18 * (21 - 12)] + (12 * 8) = 258 ft²
The area of the L shaped figure is 258 ft²

Answer:
the slope of 15 is more difficult to run on
Step-by-step explanation:
The larger the slope, the steeper the ramp. A slope of zero is a horizontal line, which would be relatively easy to run on. A slope of undefined is a wall, which we cannot run on (we would fall off). The larger the number, the steeper it gets
