I’m so confused what are u trying to ask
it equals <span>(−<span>12</span>)</span> because <span><span>cos<span>(<span>60∘</span>)</span></span>=<span>12</span></span>
Explanation:
The reference angle for <span>240∘</span> is <span>60∘</span> (since <span><span>240∘</span>=<span>180∘</span>+<span>60∘</span></span>)
<span>60∘</span> is an angle of one of the standard triangles with
<span><span>cos<span>(<span>60∘</span>)</span></span>=<span>12</span></span>
<span>240∘</span> is in the 3rd quadrant so (either by CAST or noting that the "x-side" of the associate triangle is negative)
<span><span>cos<span>(<span>240∘</span>)</span></span>=−<span>cos<span>(<span>60∘</span>)</span></span></span>
<span><span>cos<span>(<span>240∘</span>)</span></span>=−<span><span>12</span></span></span>
Complete Question
The diagram for the question is shown on the first uploaded image
Answer:
The final position of Karel is shown on the second uploaded image
Step-by-step explanation:
On the diagram the dot represents steps to be taken by Karel
Now after Karel the Dog has moved forward three spaces, Karel will be standing on a ball, so Karel will turn right move forward two spaces
So the final position of Karel is shown on the second uploaded image
Answer:
A)Points are A ,B,C,D,G,E
B) other names are AC, CA, ABC
C)the Rays are DE, DG
D) M refers to the plane in which these points and Rays,lines are mentioned
E) < GDE < EDG are other names for angle 1
Explanation:
A line is one which has arrow heads on both ends and extends infinitely .
A ray has arrow Head at one end.
An angle is formed by the joining of two rays or lines.
Points are specific locations on a line or ray .
A plane has two dimensions length and breadth which has a line etc drawn on it
I believe the answer should be 77
