that question doesnt make sense!
The top later is 5 because if the ladder is 10 inches half is 5 and the other half is 5
Answer:
0=8
1=9
2=10
3=11
graph 2
Step-by-step explanation:
We know that
<span>The cosine of the sum of two angles </span><span>is defined by the following trigonometric identity
</span>cos(A + B) = cos A cos B − sin A sin <span>B
A=60</span>°
B=105°
cos A=cos 60
cos B=cos 105
sin A=sin 60
sin B=sin 105
then
cos(60 + 105) = cos 60 cos 105 − sin 60 sin 105
cos(165) = cos 60 cos 105 − sin 60 sin 105
the answer is
cos (105°)
