thanks for your help I really think that it's three
<span>-3(5+8r)=33-8r
-15 - 24r = 33 - 8r
-15 - 33 = - 8r + 24r
-48 = 16r
-48/16 = r
-3 = r
r = -3</span>
Sorry I don’t know the answer hope you find one bye halleluja
Answer:
m∠DEC = 78°
Step-by-step explanation:
Given information: AC = AD, AB⊥BD, m∠DAC = 44° and CE bisects ∠ACD.
If two sides of a triangles are congruent then the opposite angles of congruent sides are congruent.
AC = AD (Given)


According to the angle sum property, the sum of interior angles of a triangle is 180°.




Divide both sides by 2.

CE bisects ∠ACD.



Use angle sum property in triangle CDE,




Subtract 102 from both sides.


Therefore, the measure of angle DEC is 78°.
The vertex of a parabola is the maximum or minimum value, and it’s represented by (x,y). The axis of symmetry is the vertical line that runs through the x axis, and also runs through the vertex. This means that the x value in the vertex (x,y) can represent the axis of symmetry.
