Step-by-step explanation:
density =mass/Volume
but Si unit of volume is m3
convert 980000cm3 into m3 by dividing with 1000000= 980000/1000000= 0.098 m3
D= M/V = 65.8/0.098= 671.43 kg/m3
14x-48x-72=3x-12-18
-34x-72=3x-30
-37x=42
x=42/-37
x=-42/37
9514 1404 393
Answer:
Step-by-step explanation:
The sum of angles in any triangle is 180°.
(x +45) +(2x +95) +(3x +48) = 180
6x +188 = 180 . . . . . . . . collect terms
6x = -8 . . . . . . . . . . . subtract 188
x = -4/3 . . . . . . . . divide by 6
Then the angles are ...
x +45 = -4/3 +45 = 43 2/3°
2x +95 = 2(-4/3) +95 = 92 1/3° . . . . the obtuse angle
3x +48 = 3(-4/3) +48 = 44°
