4x + 12 = 12 one solution

x=0

Step-by-step explanation:

4x+12=12

-12      -12

4x=0

x=0

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
