Answer:
B.76 square feet
Step-by-step explanation:
SA=B+L
A_{5} = a_{1} + 4d = -5 + 4 x 6 = 19
There has been 28 years since 1985 to 2013, this becomes your x value. Plug x into the equation:
f(x) = (.65*28)+24.75
f(x) = 18.2+24.75
f(x) = 42.95
Answer:
Step-by-step explanation:
Sin(x) = opposite / hypotenuse.
opposite = 28 The opposite is not connected to the angle.
hypotenuse= 35
Sin(x) = 28/35 = 4/5
Cos(x) = adjacent / hypotenuse.
The adjacent side is part of the angle
adjacent = 21
hypotenuse = 35
Cos(x) = 21 / 35 = 3/5
Tan(x) = opposite / adjacent
opposite = 28
adjacent = 21
Tan(x) = 28/21
Tan(x) = 4/3
Answer:
D. 8
Step-by-step explanation:
Draw segment CQ which will be perpendicular to tangent PR.
So, triangle CQR will be right angled triangle right angle at Q.
Let radius of the circle be r.
Therefore,
CQ = CS = r
By Pythagoras Theorem:
