Answer:
y+(21)=-4(x-7)
Step-by-step explanation:
the point slope equation , two point
m=y2-y1/x2-x1
m=23+21/-4-7=44/-11= -4
y+(21)=-4(x-7)
Answer:
Step-by-step explanation:
Using the cosine theorem:



The angle is 114.014 degrees if we substract 90 degrees it means that at point L the plane changed its angle by 24 degrees
1 - 2/3 - 1/4
= 1 - 8/12 - 3/12
= 1/12
