Answer:
Step-by-step explanation:
The sum of the angle measures of a triangle is 180°. Find the value of x . Then find the angle measures of the triangle.
find the value of x
x + 2x + x + 8 = 180
4x = 180 - 8
4x = 172
x = 172 : 4
x = 43
find angles
2x = 43 * 2
2x = 86°
-------
x = 43°
--------
x + 8 = 43 + 8
x = 51°
-----------------------
check
86 + 43 + 51 = 180°
the answer is good
Answer:
Step-by-step explanation:
That creates the number 82,190
The volume of the cube is 6*6*6 (in cubed)=216 (in cubed).
in 1 cubic inch, there is 0.5 lb of weight
so in 216 cubic inch, there are 216*0.5 lb = 108 lbs of weight
Answer: 108 lbs
