There is no solution since ln(0) is undefined
Angle-5 and angle-7 are 'vertical angles', so they're equal,
and we can write ...
<u>10x- 9 = 9x</u>
Subtract 9x from each side: x - 9 = 0
Add 9 to each side: <u> x = 9</u>
Now that we know what 'x' is, we can find the size of Angles-5 and -7 .
Angle-7 = 9x = 81° .
Now look at Angle-6 ... the one that's the answer to the problem.
Angle-6 and -7 together make a straight line, so they must
add up to 180°.
<u>Angle-6 + 81° = 180°</u>
Subtract 81° from each side: Angle-6 = <em>99° .</em>
Answer:
Radius = 4.95 cm
Step-by-step explanation:
I am assuming you need the radius of the base of the cylinder.
Volume = 1.54 * 1000 = 1540 cm^3
Volume = πr^2h so:
1540 = π*r^2*20
r^2 = 1540/20 π = 24.510
r = 4.95 cm.
