Jawab:
(a.) x = 9
(b.) x = 12
(c.) a = 9 inci
(d.) a = 4 m
(e.) x = 10
(f.) c = 12 kaki

Penjelasan dengan langkah-langkah:

(a.) Salah gambarnya
Harusnya sisi miring yang 15, depan yang x
Tripel pythagoras dasar
{3, 4, 5}
jika dikalikan 3 =
{9, 12, 15}
x = 9

(b.) Tripel pythagoras dasar
{5, 12, 13}
x = 12

(c.) Tripel pythagoras dasar
{28, 45, 53}
jika dikali 0,2
{28×0,2, 45×0,2, 53×0,2}
{5,6, 9, 10,6}
a = 9 inci

(d.) Tripel pythagoras dasar
{5, 12, 13}
jika dikalikan 0,8 =
[5×0,8, 12×0,8, 13×0,8}
{4, 9,6, 10,4}
a = 4 m

(e.) Tripel pythagoras dasar
{3, 4, 5}
jika dikalikan 2 =
{3×2, 4×2, 5×2}
{6, 8, 10}
x = 10

(f.) Tripel pythagoras dasar
{3, 4, 5}
jika dikalikan 24 =
{3×2.4, 4×2.4, 5×2.4}
{7.2, 9.6, 12.0}
c = 12 kaki
