Answer:
4(x^2 +10 +21)
4(x+3)(x+7) = 0
Smaller
4(x+7) = 0
4x +28 = 0
4x = -28
x = -28/4
x = -7
Larger
4(x+3) = 0
4x + 12 = 0
4x =-12
x = -12 / 4
x = -3
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
Using the exact values of the trigonometric ratios
sin60° =
, cos60° = 
sin45° = cos45° = 
Using the sine ratio on the right triangle on the left
sin60° =
=
= 
Cross- multiply
2a = 4
×
= 12 ( divide both sides by 2 )
a = 6
Using the cosine ratio on the same right triangle
cos60° =
=
= 
Cross- multiply
2c = 4
( divide both sides by 2 )
c = 2
------------------------------------------------------------------------------------------
Using the sine/cosine ratios on the right triangle on the right
sin45° =
=
= 
Cross- multiply
b = 6
cos45° =
=
= 
Cross- multiply
d = 6
( divide both sides by
)
d = 6
------------------------------------------------------------------------------------------------
a = 6, b = 6
, c = 2
, d = 6
Y equals 48 because it’s a rise of 1 over 4
