GIVEN TRIANGLE PQR WITH P(1,6) Q(3,1) AND R(8,3). WHAT POINT BISECTS PQ? B) WHY DO SLOPES OF THE PQ AND QR SHOW THAT M
Step-by-step explanation:
Ok let's do this*pops knuckles*
let's add the first side

order of operations demands that we do multiplication first(P.E.M.D.A.S)
so

now we can add the 1 from

into our six

now we substract

now we have

now we focus on the
other side

since 5 is in paranthesis we use something called the distributive property. it mean we will multiply the 5 by both of the 2.

now we have

(the three is from the original equation)
now we plug in our final numbers

or

I hope this helps
Answer:
<h3>83°</h3>
Step-by-step explanation:
Given the parameters
m2 ROC = 31° and
m2 COL = 52°
According to the diagram in the attachment;
m2 ROL = m2 ROC + m2 COL
Substitute the given values into the expression as shown;
m2 ROL= 31°+52°
m2 ROL = 83°
Step-by-step explanation:
1. You already got the first step, where D is the midpoint of AC and AB is congruent to BC, since it's given.
2. AD will be congruent to DC, via the definition of a midpoint (a midpoint is the middle point of a line segment, and it splits the segment into two congruent parts)
3. BD is equal to BD, via reflexive property. ( It's a shared side between the two triangles)
4. that means that ΔADB ≅ΔCDB via SSS rule.
5. ∠ABD ≅∠CDB by CPCTC (corresponding parts of congruent triangles are congruent)
Hope this helps! :)
