Answer:
30
Step-by-step explanation:
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.
Answer:
843
Step-by-step explanation:
357+486=843 just add
SinØ(TanØ+2)=3cosØ -----[pulling like terms out]
for the following steps The easiest 4 me is that I just plug in values between 0° and 180° for Ø and see which will help me to get equal numbers on both sides.
So, for instance if you use Ø=90°, you'll get the following, Sin90(Tan90+2)=3cos90
========> 1(1+2)=3(1) ==> 3=3
so 90° is one of the solutions ur looking for.
hope this was helpful
