The formula for the area of a rectangle is A = bh.
Substitute 216.24 for A (area) and 15.9 for h (height).
A = bh
216.24 = b(15.9)
÷ 15.9 ÷ 15.9 Divide 15.9 on both sides.
13.6 = b
So, the base of the rectangle is 13.6 cm.
Answer:
1 - cosΘ
Step-by-step explanation:
using the identity
sin²x + cos²x = 1 , then
sin²x = 1 - cos²x
= 
← factor 1 - cos²Θ as a difference of squares
= 
← cancel 1 + cosΘ on numerator/ denominator
= 1 - cosΘ
(-5C^2)^3-(5c)^6
-125C^5 - 15625c^6
