Answer:
15°
Step-by-step explanation:
AB is parallel to DC and AD is parallel to BC
Therefore, if you put Angle D and Angle C together it must form 180°
If Angle C = 120°, that means Angle D = 60°
Now you subtract 45 from 60 and that gives you 15.
Answer:
C' (- 3, 2 )
Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y ) , then
C (3, 2 ) → C' (- 3, 2 )
Hello :
the center of this cercle is : O( 0, 0)
calculate the slope m of the line : OA .. A (3,-4)
m= (yA - yO) / (xA- xO)
m = (-4-0)/(3-0)
m= -4/3
if : k the slope of the tangent : k×m = -1 (the tangent perpendiclar of : OA)
k× (-4/3) = -1
k = 3/4
an equation of this tangent is : y - (-4) = (3/4)(x-3)
Answer:
if there can be no more than 5 students, then anything less than 5 students will suffice. However we don’t want any left over ones cause we don’t want that one kid sitting alone during lunch so we can simply put <u><em>4 into each group.</em></u>
