Answer:
θ = 18°27'
Step-by-step explanation:
As the hint says, you need to calculate CE using the triangles ΔABC and ΔBDE.
Using segment addition, CE = CB + BE. So first use trigonometry to find these segments.
First, let's find CB.
sin 22° = CB / 4.882
CB = 1.8288
Next, let's find BE.
cos 22° = AB / 4.882
AB = 4.5265
BD = AB − 1.975
BD = 2.5515
tan 48° = BE / BD
BE = 2.8337
Now we can find CE and θ.
CE = CB + BE
CE = 4.6626
cos θ = CE / 4.915
θ = 18.443°
A minute is 1/60th of a degree.
0.443° × (60 '/°) = 27'
So θ = 18°27'.
Answer: 1 3/12
Step-by-step explanation: You can multiple straight accross and
5 is equivelant to 5/1 so we would do
5/1 * 3/12 = 15/12 which can get simplified into 1 3/12
Hopt this helps :D
Answer: (8)(-4.5)
Step-by-step explanation: If you were to multiply -4.5 • -8 it would be a positive number but if you multiply (8)(-4.5) that would equal a negative number
When a line changes position from one point to another, the movement is referred to as transition.
<em>Bobby does not have enough information to make a valid conclusion.</em>
The movements of the lines are given as:
<em>Line 1: 3 units up and 8 units right</em>
<em>Line 2: 8 units down and 3 units right</em>
The given information only describes the movement of both lines, but does not give details about the initial relationship between the lines.
<em>Hence, no valid conclusion can be made with the given information.</em>
