Answer:
sin (55) = DE / AD
AD = DE / sin (55)
AD = 8 / sin (55)
And
tan (55) = DC / AD
tan (55) = DC / [8 / sin (55) ]
DC = 8 tan (55) / sin (55)
AD * DC =
[8 /sin (55) ] [ 8 tan (55) / sin (55) ] = 136 units^2

Answer:
(2x +3 )(x-5)
one is the length and one is the width
Step-by-step explanation:
2x^2-7x-15
Factor
(2x )(x )
What are the factors of -15? -1*15 and -3*5, 3*-5 , 1*-15
We need 2* one factor ± the other factor = -7
2*-5 +3 = -7
That means the -5 is on the outside and the +3 is on the inside
(2x +3 )(x-5)
Answer:
-4/5
Step-by-step explanation:
Lets put the equation in slope intercept form
4x+5y = -20
Subtract 4x from each side
4x-4x+5y = -4x-20
5y = -4x-20
Divide each side by 5
5y/5 = -4x/5 -20/5
y = -4/5 x -4
The equation is in the form y = mx+b where m is the slope and b is the y intercept
the slope is -4/5 and the y intercept is -4
Answer:
5/10 + 3/10 = 8/10
5/10 - 3/10 = 2/10
Step-by-step explanation:
1/2 = 5/10
5/10 + 3/10 = 8/10
5/10 - 3/10 = 2/10
