5. <LKM = 50⁰, <KLM = 70⁰, <LMK = x( sudut dalam segitiga )

a. <LKM + <KLM + <LMK = 180⁰( sudut dalam segitiga )

50⁰ + 70⁰ + x = 180⁰

120⁰ + x = 180⁰

x = 180⁰ - 120⁰

x = 60⁰

<LMK + <KMN = 180⁰( sudut berpelurus )

60⁰ + 2y = 180⁰

2y = 180⁰ - 60⁰

2y = 120⁰

y = 120⁰/2 = 60⁰

Jadi, nilai x dan y sama-sama 60⁰
