a^2 + b^2 = c^2
a = sqrt(c^2 - b^2) = sqrt (20^2 - 16^2)
= 12
sin
= a/c = 12/20
= 3/5
cos
= b/c = 16/20
= 4/5
tan
= a/b = 12/16
= 3/4
csc
= c/a = 20/12
= 5/3
= 1 2/3
sec
= c/b = 20/16
= 5/4
= 1 1/4
Answer:
$20000
Step-by-step explanation:
6*10^12/ 300 million
3(2y + 4) = 4(2y - 1/2)
Distributive property on both sides.
5y + 12 = 8y - 2
+2
5y + 14 = 8y
-5y
14 = 3y
/3
y = 4.66
9x^2 + 24x + 16 = (3x + 4)(3x + 4)length of each side = 3x + 4 units.
16x^2 - 25y^2= (4x + 5y )( 4x - 5y)
length = 4x + 5y and width = 4x - 5y
