Answer:
Actual width = 5 feet.
Step-by-step explanation:
The ratio of 1.2 to 1 equals the ratio of length to width.
1.2 / 1 = 6 / w where w is the actual width.
1.2w = 6
w = 6/1.2
w = 5.
Answer:
Step-by-step explanation:
ahh this is a really tough one :D Does this happen to be an AP math class, Pineapple .. you are in advanced math :O.... good for you :)
sooo what can we set equal
note the lines have the same lenght, therefore the arc length will also be the same, then they give us the other two lengths to make the entire circle , yay
so then just set all the arc lengths equal to 360 °
(3x+ 30) + (3x + 30 ) + 2x + 4x = 360 ( put like terms together )
12x + 60 = 360 ( subtract 60 from both sides )
12x = 300 ( divide both side by 12 )
x = 25
nice we now know X :)
Answer:
The area of a rhombus is square units.
Step-by-step explanation:
Side length of rhombus = 6 units.
Interior angle of rhombus = 120°
another Interior angle of rhombus = 180°-120° = 60°.
Draw an altitude.
In a right angled triangle
Multiply both sides by 6.
The height of the rhombus is .
Area of a rhombus is
Therefore, the area of a rhombus is square units.
