Answer:
The area of the field = 19966.21 units²
Step-by-step explanation:
* Lets explain how to find area of a triangle by trigonometry rule
- In any triangle if you have the lengths of two sides and the measure
of the including angle between these two sides, then the area of the
triangle is A = 
, wher α is the
including angle between them
* Lets solve the problem
∵ The field is shaped triangle
∵ The lengths of two sides of the field are 218.5 and 213.3
∴ s1 = 218.5
∴ s2 = 213.3
∵ The measure of the angle between the two sides is 58.96°
∴ α = 58.96°
- Lets find the area using the rule of trigonometry
∴ 
∴ The area of the field = 19966.21 units²
So Length * Width = 480 in. sq.
L=1 1/5 or 1.2W
substitute the L for 1.2W
1.2W*W=480 in sq
divide both sides by 1.2
w*w= 400
W²=400
square root of both sides
Width = 20 inches
Length= (1.2width) or (20*1.2)
Length=24 inches
Answer:
B.
Step-by-step explanation:
Answer:
tkae j ad by f then subtracr the u then add the c then multply k then say u
Step-by-step explanation:
We have been that frequency (y) varies inversely with wavelength (x).
We know that two inversely proportional quantities are in form 
, where a is inversely proportional to b and k is constant of variation.
Our required equation would be 
.
To find frequency of blue light, we will substitute 
and 
in our equation as:
Therefore, the frequency of blue light is 764.
