Answer:
26.39
Step-by-step explanation:
sin B = 4/9
B = inverse sin 4/9 = 26.387
So the side length became 0.6*5 = 3 cm.
In regular polygons, if the number of sides, n, is odd, the lines of symmetry will pass through a vertex and the half of the opposite side.
Step-by-step explanation:
This is equivalent to say that a perpendicular bisector of a side of the regular polygon bisects the angle of the opposite vertex to the side, and divide the polygon into two symmetrical parts.
You have a bag containing 8 + 20 = 28 marbles.
After you pull a black marble you have 28 - 1 = 27 remaining marbles.
There are 20 yellow marbles in the bag.
The probability of pulling a yellow marble is now

Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
4x - 5 = x - 1 + 3x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 4x - 5 = 4x - 1
- Subtract 4x on both sides: -5 ≠ -1
Here we see that -5 does not equal -1.
∴ This equation has no solutions.
