- Reading a Cartesian Plane
Step-by-step explanation:
When we label a Cartesian Plane, we label counterclockwise starting at the top right corner:
Top Right Corner = 1st Quadrant
Top Left Corner = 2nd Quadrant
Bottom Left Corner = 3rd Quadrant
Bottom Right Corner = 4th Quadrant
We see that point B is in the Bottom Right Corner. Therefore, it is in the 4th Quadrant and our answer would be D.
Nine hundred forty one thousandhs
Answer:
<em>Option D is correct</em>
Step-by-step explanation:
Applying the cosine theorem for triangle ABC, you would have:
cos (angle BAC) = (BA^2 + CA^2 - BC^2)/(2*BA*CA)
= (10^2 + 18^2 - 20^2)/(2*10*18)
= 24/360
=> angle BAC = ~86 deg
Hope this helps!
Answer:
Option D 74°
Step-by-step explanation:
we know that
The measurement of the outer angle is the semi-difference of the arcs it encompasses.
so
The arcs that the outer angle encompasses are
254° and (360-254)=106°
therefore
∠x=(1/2)[254°-106°]
∠x=(1/2)[148°]
∠x=74°
