So for perimeter you need to find out the total of all the sides. To find out side AB, you make a triangle and find out the hypotenuse.
a=5 and b=6
a square= 25 b square= 36
25+36= 61
Square root of 61 is 7.81
So side AB is 7.81 ft
Now we need to find out side BC.
a=3 and b=4
a square is 9 and b square is 16.
9+16 is 25
Square root of 25 is 5
Side BC is 5 ft.
Because it's a rectangle, side CD will be 7.81 and side DA will be 5.
7.81*2+5*2= 25.62 ft
So the perimeter of the rectangle is 25.62 ft or C.
Answer:
The triangles are ASA. hope this helped
<h3>
Answer: C) 4/8 = 0.5</h3>
=========================================================
Explanation:
The sine ratio involves the opposite over hypotenuse.
With respect to reference angle J, the opposite leg is the one furthest from the angle. So the opposite side is KL = 4. The hypotenuse is always the longest side, always opposite the 90 degree angle, so LJ = 8 is the hypotenuse.
sin(angle) = opposite/hypotenuse
sin(J) = KL/LJ
sin(J) = 4/8
sin(J) = 0.5
Given:
Consider the number as <em>x</em>.
The objective is to represent algebraic expression for, 2 is subtracted from the square of a number.
Explanation:
Since the number is given as <em>x</em>, the square of the number can be represented as,
Now, subtract 2 from the above expression,
Hence, the required expression is x²-2.
Answer 16 cubic cm (cm^3)
Volume of a cube is L x W x H
Since the cube has equal sides of 4 cm
4 x 4 x 4 = 64 total volume of cube
Now we take 25% of the cubes total volume to find the portion filled with sand
25% x 64 = 16 cubic cm
