Answer: 51.9 degrees
Step by step explanation:
Sin(71)/35.6=Sin(x)/21.3
21.3Sin(71)=35.6Sin(x)
21.3Sin(71)/25.6=sin(x)
Sin^-1(21.3Sin(71)/25.6)=x
51.87827502 degrees=x
51.9= angle x
Answer:
<h2>A = 82.5 in²</h2>
Step-by-step explanation:
The formula of an area of a trapezoid:
b₁, b₂ - bases
h - height
We have b₁ = 10in, b₂ = 5in and h = 11in. Substitute:
Answer:
Step-by-step explanation:
The formulas to find the radius are quite simple. If you know the diameter of the circle, use this formula:
If you don't know the diameter, but you know the circumference, you can use this equation:
If you know the area of the circle, use this equation:
Note that the area of a circle is essentially the total space, measured in square units, inside of the perimeter of a circle.
80 percent of needed milligrams is 1360
so
1360/.80 = x/1
Answer: 1700 milligrams
