Querying custom post type with two criteria

Thanks in advance for any help.
I’ve created a page that lists the taxonomy of a custom-post-type. The issue I’m running into is I’ve created a page that should only pull the category and a placement code (in the example that’s standard). It’s pulling the placement but how do I get it to add in the dynamically created category pulled from the previous page.

Code that dynamically pulls taxonomy (category header). This pulls the right category on the page.
$term = get_term_by( ‘slug’, get_query_var( ‘term’ ), get_query_var( ‘taxonomy’ ) ); echo $term->name;

Code below that pulls on the particular placement. How do I add the dynamically pulled taxonomy pulled by code above so content meets both criteria.

$args = array(
	'post_type' => 'buyersguide',
    'meta_query' => array(
        array(
            'key' => 'Placement',
            'value' => 'standard',
            'compare' => 'LIKE'
        )
    )
);
query_posts($args);
