Answer:
1. 3-4-5 method
2. Rope method
3. Optical square method
Step-by-step explanation:
1. You'll need a measuring tape, two range poles, pegs, and three people.
The first person holds the zero mark between their thumbs and fingers, the second person holds the 3m mark on the tape between their thumbs and fingers, and the third person holds the 8m. When all sides of the rope are stretched, a triangle is created, and an angle near one is a right angle.
2. Wrap one loop of the rope around peg A with a peg through the other loop, draw a circle on the ground, place pegs B and C where the circle crosses the base line, and place peg D half way between pegs B and C, allowing pegs D and A to form lines perpendicular to the base line, forming a right angle.
3. Single and double prismatic squares are basic devices used to measure correct angles.
Answer:
12x-4
Step-by-step explanation:
combine like terms. the 5x with the 7x (=12x) and the 3 witht the -7 (-4) hope this helps!!
Answer:
Part A) The area of one rectangular mat is 18 ft^2
Part B) The length of the rectangular mat is 6 ft and the width is 3 ft
Step-by-step explanation:
see the attached figure to better understand the problem
Part A) Write and solve an equation to find the area of one rectangular mat.
Let
x ------> the area of a square mat
y ------> the area of one rectangular mat
we know that
-----> equation A
-----> equation B
substitute equation B in equation A and solve for y



therefore
The area of one rectangular mat is 18 ft^2
Part B) The length of a rectangular mat is twice the width. Find the dimensions of one rectangular mat.
Let
L -----> the length of rectangular mat
W -----> the width of rectangular mat
The area of rectangular mat is


so
----> equation A
-----> equation B
substitute equation B in equation A and solve for W


Simplify

square root both sides

Find the value of L

therefore
The length of the rectangular mat is 6 ft and the width is 3 ft
