In ∆ABC if <A=56°<=68° find <b plss helpp​

I'm assuming you mean that <C=68 degrees.

Now we know that the interior angle of a triangle adds up to 180 degrees.

We just need to subtract the 2 already known angles from it.

180 degrees-56 degrees-68 degrees=180 degrees-124 degrees=56 degrees.

Done!

<B=56 degrees.

Any questions you can ask in the comments, also something to look out for always capitalize your letter when you are writing angles :)!

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
