If the measure of angle 4 is 94°, each angle congruent to it will be 94°. Angles 2, 4, 6, and 8 are the same and the angles 1, 3, 5, and 7 are the same. The straight line (I believe it's a transversal) divides the parallel lines and it is slightly tilted, which is why angles 2, 4, 6, and 8 are 94° instead of 90°.

The angle of say, 2 and 3 added, is equal to 180° which makes it supplementary. That means if we know angle 2 is 94°, we can subtract that from 180° to find the angle of 3 and the subsequent odd angles. 180 - 94 = 86 so angles 1, 3, 5, and 7 are 86°.

Hope this helps

For what value is x+4/5x-9 undefined?

pochemuha

Hello from MrBillDoesMath!

Answer: x = 9/5

Discussion :

The quotient is undefined when the denominator = 0. i.e. 5x - 9 = 0

5x - 9 = 0

5x = 9 (add 9 to both sides)

x = 9/5 (divide both sides by 5)

We have been given that Maria put trim around a banner that is the shape of a triangle. Each side is 21 inches long.

The amount of trim will be equal to perimeter of triangle. The perimeter of given triangle will be 3 times each side length that is $3\times 21=63$ inches.

Now we need to convert 63 inches into feet.

12 inches = 1 feet

63 inches = $\frac{63}{12}$ feet = 5.25 feet.

We are also told that Maria has $\frac{3}{4}$ foot of trim left, so total length of trim would be trim used plus trim left that is $5.25+\frac{3}{4}=5.25+0.75=6$ feet.
