Tentukanlah nilai x×y+z
Jawab: X x Y + Z = 65 x 25 + 10
Penjelasan dengan langkah-langkah:
2x=130
x=130/2 = 65
3y=75
y=75/3=25
55 = 5z+5
5z=55-5
5z=50
z=50/5 =10
x=65, y=25, z=10
x.y+z = 65 x 25 + 10
Jawaban:
cari nilai x
2x = 130°
x = 130°/2
x = 65
cari nilai y
3y = 75°
y = 75°/3
y = 25
cari nilai z
5z + 5 = 55°
5z = 55° - 5
5z = 50
z = 50/5
z = 10
tentukan nilai x × y + z
x × y + z
= 65 × 25 + 10
= 1.625 + 10
= 1.635
