Answer:
Step-by-step explanation:
Total interior angles in a triangle=180 degrees
That is: 3x + 10 + 5x - 1 + x =180
9x+9=180
9x=180-9
9x=171
x=171/9
x=19
Therefore
Angle A =67 degrees
Angle B= 94 degrees
Angle C = 19 degrees
Answer:
40 mm
Step-by-step explanation:
The rectangular prism of a rectangular box. The volume is given by the formula:
<u>Volume of Rectangular Prism</u> = length * width * height
Given Volume = 3200
Length = 10
Width = 8
We need to find height. So we plug in the given information and find the height, in mm. Shown below:
Volume = Length * Width * Height
3200 = 10 * 8 * Height
3200 = 80 * Height
Height = 3200/80
Height = 40 mm
The height (h) = 40 mm
