What is x+ (5x-18)+90 degrees

Mathematics
1 answer:
sweet [91]3 years ago
5 0

As this is an expression, not an equation, you cannot find a value for x. We can combine like terms, as follows:

x + (5x - 18 ) + 90

x + 5x - 18 + 90

6x - 72 or 6(x-12) : simplest form of this expression

Ruben has two congruent wooden dowels. He cuts one dowel in two in order to have three pieces to make a triangle. Explain why, d
e-lub [12.9K]
Let us use the Pythagorean theorem in identifying what triangle can be formed.

Let us assume that the 2 wooden dowels each measure 8 inches. We cut off one wooden dowel into half, so it becomes 2 pcs of 4 inches each.

The 3 wooden dowels now measure, 4 inches, 4 inches, and 8 inches. 

The Pythagorean theorem states: 

a² + b² = c²
4² + 4² = 8²
16 + 16 = 64
34 ≠ 64

The measure of the cut wooden dowel must be longer than the uncut wooden dowel to create a triangle. 

I also tried this on a piece of paper, I cut each piece according to the assumed measure. No triangle can be formed under this activity.
