Answer:
Since i don't know what formula is mentioned. I just used the easiest way to solve :)
Step-by-step explanation:




Answer:
186
Step-by-step explanation:
1/3 would be 62. You get it by dividing 124 by 2.
Add the 62 onto 124
You would set it up like this: 150x + 280 = 255x The you just solve.
Answer:

Step-by-step explanation:
Given
The attached rhombus
Required
The area
First, calculate the length of half the vertical diagonal (x).
Length x is represented as the adjacent to 60 degrees
So, we have:

Solve for x


So:


At this point, we have established that the rhombus is made up 4 triangles of the following dimensions


So, the area of the rhombus is 4 times the area of 1 triangle




Area=pi times radiius^2
radius=diameter/2
diamter=5
radius=5/2=2.5
pi=3.14 aprox
area=3.14 times 2.5^2
area=3.14 times 6.25
area=19.625 ft^2
round
19.6 round up
20
the answer is 20 ft^2
