<h2>Hello There today we will solve your problem</h2>
<em>85% of the students in Yvan’s school walk to school. If 816 students walk to school, how many students are in the school?</em>
<em />
<em>Response-</em>
Since we are using percents we can make an equation out of this question
is the way we write percents in math as a fraction
and 
is the part and whole you gave us
cross multiply
students are in the school
students at Y'vans school
Answer:
$13.75 , $11.25
Step-by-step explanation:
If they took off 45% of the original price, that means you gotta subtract
$25 - 45% = 13.75
to find the amount of the discount, subtract 13.75 from 25
$25-$13.75 = $11.25
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 .

so... that's how much an internal angle is
now, subtract that from 180 and you get the angle outside, in the picture
subtract that outside angle twice from 180, and you get angle "2"
because angle 2 is in the same triangle as those two outside angles, and all internal angles in a triangle is 180, thus 180 - (those two angles) is angle "2"
