When we draw a circle with the centre at D and have a tangent HF to the circle D at point E, the angle DEF will be a right angle.
In other words angle DEF = 90 degrees
Since HF, the tangent, is a straight line, the other angle DEH should also be = 90 degrees because the straight line has an angle of 180 degrees
Therefore angle DEF = angle DEH = 90 degrees
Therefore, angle DEF is congruent to angle DEH (Option A)
X-int:let y=0
3x-2(0)=18
3x=18
divide both sides by 3
therefore x=6
y-int:let x=0
3(0)-2y=18
-2y=18
we divide both side by -2
therefore y=-9

e = k.m
360 = k.60
k = 360/60 = 36/6 = 6
108 = 6.m
108/6 = m = 18
6 x² y³ / 24 x³ y²
Divide numerator
and denominator by x² : 6 y² / 24 x y²
Divide numerator
and denominator by y² : 6 / 24x
Divide numerator
and denominator by 6 : <em> 1 / 4x </em>
Answer:
Step-by-step explanation:
3,5,6,
a =3
d = 5-3 = 2
Tn= a+(n-1)d
T6= 3+(6-1)2 = 3 + (5)2 = 3 + 10 = 13
