The statements that are true are AD = BD , m∠ACD = m∠BCD , m∠CDA = m∠CDB , Option A , C and D
<h3>What is a Triangle ?</h3>
A triangle is a polygon with three sides , angles and vertices.
It is given a Δ ACB
CD is the angle bisector of ∠ACB
AC ≅ CB
To determine which statement are true
First it has to be proved that Δ DCB is congruent to Δ ACD
In the triangles
AC = CB (Given )
∠ACD = ∠DCB (CD is the angle bisector of ∠ACB)
DC = DC ( Common side )
thus Δ DCB is congruent to Δ ACD
Therefore the following statements are true
AD = BD (CPCTC)
m∠ACD = m∠BCD (CPCTC)
m∠CDA = m∠CDB (CPCTC)
Therefore Option A , C and D are the statements that are true .

Hello there,
12in.*7 days= 84in.
Not totally positive with my answer but I'm still thinking.
The speed that Morris is travelling is 0.3 ft/s
<h3>Calculating the speed of a body</h3>
Speed is the ratio of distance covered with respect to time.
Given the following parameters
Speed of Annesha = 50mi/hr
Speed of Moris = 3ft/s less than Aneesha
Convert 50mi/hr to ft/hr
50mi/hr = 73.3ft/s
Speed of Morris = 73.3 - 3
Speed of Morris =70.3 ft/s
Hence the speed that Morris is travelling is 0.3 ft/s

Answer:
width = 2.5 feet
Step-by-step explanation:
Suzanne has a rectangular garden which is 18 feet long and 11 feet wide.
Area of the garden = length times width = 18 times 11= 198 square foot
Let 'w' be the width of the border
Length of the garden with border = 18+2w
Width of the garden with border = 11+2w
Area of the garden with border = 
Area of the border = 
She has 168 square foot of paving stones,
Solve for w
apply quadratic formula
a= 4, b= 58 and c=-168
we get two values for w
