Answer:
10a + 2b
Step-by-step explanation:
Add the lengths of all sides:
3a + b + b + 2a - b + 3a + b + b + 2a - b
Now combine like terms:
10a + 2b
I believe it’s 5,193.0315 I’m not to sure
Width = 4ft
Length = 6ft
<u>Explanation:
</u>
Let length = l ,
So, width = 2l-8
Perimeter of rectangle = 2x(length + width)
According to the question,
Hence,
Width = 4ft
Length = 6ft
Answer:divide the opposite sides, by the length of the hypotenuse. To get the cosine, divide the length of the adjacent side,by the length of the hypotenuse.
Step-by-step explanation:
divide the opposite sides, by the length of the hypotenuse. To get the cosine, divide the length of the adjacent side,by the length of the hypotenuse.
Answer:
42°
Step-by-step explanation:
Sum of all the angles inside of any triangle is always 180°.
Therefore:
180 = y + 90 + 48
y = 180 - 90 - 48
y = 42°
