What are you trying to find?
Using the
solver function of the calculator, we can find the roots of the polynomial.
x1
= 9.72484
x2 = −5.36242+8.74882i
x3 = −5.36242−8.74882i

Since
dimension cannot be imaginary, therefore the height of the cylindrical hole is
9.72 mm.
Calculating
for radius r:
r
= 9.72 mm – 8 mm
r
= 1.72 mm
The
volume of cylinder is given as:
V
= π r^2 h
V
= π (1.72)^2 (9.72)
<span>V
= 90.34 mm^3</span></span>

Answer:
1. x = 30
2. x = 39
Step-by-step explanation:
1.
4x and ( 3x + 30 ) are alternate exterior angles,
Alternate exterior angles are equal.
4x = 3x + 30
4x - 3x = 30
x = 30
2.
x and ( 3x + 24 ) are co - interior angles.
Sum of co - interior angles is 180,
x + 3x + 24 = 180
4x + 24 = 180
4x = 180 - 24
4x = 156
x = 156 / 4
x = 39
Answer:
x = 6.5
Step-by-step explanation:
* since it's a triangle ALL the angles inside should give you 180° * Equate everything to 180°
8x + 10x - 10°+ 10x + 8° = 180°( sum of angles on a triangle)
28x - 2° = 180° * group like terms*
28x = 182°
x = 6.5
