Tricky one because they're asking for C not x.
2x + 2x + 6x = 180
10x = 180
x = 18
C = 2x = 36
Last one
Check the picture below.
notice AB ⟂ BC , whilst ∡B = 30°.
now, if we run a perpendicular line from C to AB, it'll be a 90° angle at M, however ∡AMC has to be 105°, so it has to be slanted more towards A, like in the picture, and surely you already know which one is the shortest.
Answer:
553.0 in³
Step-by-step explanation:
(please see attached for reference)
Assuming you are asked to find the volume,
the volume of the cylinder is given by
V = πr²h
where,
π=3.142
r = given as 4 inches
h = given as 11 inches
Substituting these values into the formula,
V = πr²h
V = 3.142 x 4² x 11
= 552.99
= 553.0 in³ (rounded to nearest tenth)
Answer:
15
Step-by-step explanation:
21 - 6 equals 15 unless if its 21 + 6 then its 27
First, you need to remember how to obtain the answer.
1) (velocity)*(cosine of the angle)2)(velocity)*(sine of the angle)
Since the plane is traveling 45 degrees below the horizon the angle that we will be using is 180+45=225.
Therefore we will have,
150* cos(225) = -81.31
150*sin(225) = -81.31
*In the unit circle, the coordinates of 225 are -squareroot(2) divided by 2 for both sin and cos, which explains why we have the same answer for both sin and cos.
The answer being negative makes sense since the speed is decreasing due to the fact that the plane is traveling below horizontal.
