Is a triangle with sides of length 6ft, 21 ft, 23 ft. a right triangle?

No

Step-by-step explanation:

By using the Pythagoras theorem, it can be easily determined that whether the triangle is right triangle or not.

Thus, where where a and b are the legs and c is the hypotenuse.

Let a=6ft, b=21ft and c=23ft, then

which is not possible, therefore the given triangle is not right triangle because it does not satisfy the Pythagoras theorem.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}
