Answer:
10
Step-by-step explanation:
given
we first need to simplify the expression before we find it's value when s=-3
positive times negative=negative
so the equation becomes
substituting s=-3 into the equation.
=
=the negatives cancel out leaving
Answer:
B
Step-by-step explanation:
By definition of supplementary angles,
∠ABD + ∠BDE = 180
5x + 17x - 18 = 180
22x = 198
x = 9
∠ABD = 5(9) = 45°
∠BDE = 180 - 45 = 135°
From the reference of the 18 degree angle, 'h' is the opposite side and 100 is the adjacent side.
The trig ratio which uses both the opposite and adjacent sides is the tangent.
tan(18) = opp/adj = h/100
Trig equation:
tan(18) = h/100
Add the prices together
Then divide by 3.
*6.25 + 3.25 = 9.50/3 = 2 of them pay 3.16 while the other pays 3.17.
