Two factory plants are making tv panels. plant a produced 2000 fewer panels than plan b did. two percent of the panels from plant a and 3% of the panels from plant b were defective. how many panels did plant a produce, if the two plants together produced 810 defective panels?

Plant A produced 15,000 panels.

Step-by-step explanation:

Let plant B produce x panels

Plant A then produced x - 2000 panels

2% of panels from plant A were defective

3% of panels from plant B were defective

The two plants together produced 810 defective panels so;

2/100(x - 2000) + 3/100(x) = 810

0.02x - 40 + 0.03x = 810

0.05x = 850

x = 17,000 panels

So plant B produced 17,000 panels

Plant A produced 17,000 - 2,000 panels = 15,000 panels.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
