Step-by-step explanation:
Each segment in ΔA"B"C" is 3 times the length of the corresponding segment in ΔABC. This is due to the dilation by a scale factor of 3.
Then you have ...
The latter relation matches the second choice.
Answer:
You need four squares.
On the top left square, you put the number 20 over it, and the number 30 to its left. Put the number 600 in the square.
Next, the bottom left square. But the number 4 on the left side of the square, and put the number 80 in the square.
Now, the top right box. put the number 8 over it, and fill it with the number 240.
Last, fill the bottom right square with the number 32.
<u>Answer:</u>
According to Question , a plane travels 120 miles in 2 hours. So here we will use unitary method .
Here it was a case of direct proportion in which if two things are directly proportional to each other. If one thing thing increases then the value of second also increases. Here if the time increases then the distance also increases
These angles are adjacent angels.
adjacent angels- have a common side and the same vertex.
(pictured below)
To solve this we set the sum of both angles equal to 180°. We do this because they are two adjacent angles on a straight line. The measure of a straight lines angle is 180°.
180= 5x + (x+96)
180=6x+96
84= 6x
x=14
