Answer:
length=52mm
Step-by-step explanation:
For an equilateral triangle A=B=C=x
perimeter= A+B+C
156=x+x+x
3x=156
x=52mm
Answer:
y - 4 = -12 ( x + 2)

Step-by-step explanation:
Answer:
Part 1) ∠MJK and ∠PJR have a unequal measures
Part 2) ∠KJL and ∠MJL have a unequal measures
Part 3) ∠LJP and ∠NJR have a equal measures
Part 4) ∠MJP and ∠PJR have a equal measures
Part 5) ∠KJR and ∠MJP have a unequal measures
Step-by-step explanation:
Part 1) ∠MJK and ∠PJR
we have that
Observing the figure
∠MJK=90°
∠PJR=48°+46°=94°
therefore
∠MJK and ∠PJR have a unequal measures
Part 2) ∠KJL and ∠MJL
we have that
Observing the figure
∠KJL=42°
∠MJL=90°-42°=48°
therefore
∠KJL and ∠MJL have a unequal measures
Part 3) ∠LJP and ∠NJR
we have that
Observing the figure
∠LJP=48°+46°+48°=142°
∠NJR=48°+48°+46°=142°
therefore
∠LJP and ∠NJR have a equal measures
Part 4) ∠MJP and ∠PJR
we have that
Observing the figure
∠MJP=46°+48°=94°
∠PJR=46°+48°=94°
therefore
∠MJP and ∠PJR have a equal measures
Part 5) ∠KJR and ∠MJP
we have that
Observing the figure
∠KJR=90°+46°+48°+48°+46°=278°
∠MJP=46°+48°=94°
therefore
∠KJR and ∠MJP have a unequal measures
