Answer:
Solve for the single variable in the one-variable equation.
Step-by-step explanation:
10 to the negative 15 (10^-15) power
Step-by-step explanation:
✰ 
- AD = 15 , AB = 8 ,
DAB
✰ 
- Height & Area of the given parallelogram
✰ 
In right angled triangle ABE :
- Hypotenuse ( h ) = 8
- Perpendicular ( p ) = h [ height ]
= 20°
Now , Using trigonometric ratio :

Plug the known values :
⟶ 
⟶ 
⟶ 
⟶ 
Now , We have :
- Base ( b ) = 15
- Height ( h ) = 2.72
Finding the area of a parallelogram whose base and height are 15 and 2.72 respectively :
❀ 
⟶ 
⟶ 
Hence , Our final answer :

Answer:
First, multiply the numbers. Then count the number of decimal places in each factor. Place the decimal in the product so the product has the same number of decimal places as both factors combined.
Step-by-step explanation:
Did it on Edg.2020
<span>r^2 = 529 - 46x + x^2 + 64
r^2 = x^2 - 46x + 593
replace r^2 with (x^2+ 225)
x^2 + 225 = x^2 - 46x + 593
x^2 - x^2 + 46x = 593 - 225
46x = 368
x = 368/46
x = 8 cm
Find the radius
r^2 = 8^2 + 225
r^2 = 289
r =
r = 17 cm is the radius</span>
