2. <A = ⅖ <B
a. Jumlah sudut berpelurus itu 180⁰ yaa
m<A + m<B = 180⁰
⅖ m<B + m<B = 180⁰
⅖ m<B + 5/5 m<B = 180⁰
7/5 m<B = 180⁰
m<B = 180⁰. 5/7
m<B = 900/7
m<B = 128,57⁰ = 129⁰
m<A = ⅖ m<B
= ⅖. 129⁰ = 51,6⁰
b. Jumlah sudut berpenyiku itu 90⁰ yaa
m<A + m<B = 90⁰
⅖ m<B + m<B = 90⁰
⅖ m<B + 5/5 m<B = 90⁰
7/5 m<B = 90⁰
m<B = 90⁰. 5/7
m<B = 450/7
= 64,68⁰ = 65⁰
m<A = ⅖ m<B
= ⅖.65⁰ = 26⁰
Selisih = m<A - m<B
= 65⁰ - 26⁰ = 39⁰
