Answer: 2014
Step-by-step explanation:
LED: -25x + 6y = 20
CFL: 15x + 2y = 322
we need to find which year it was the same to know where LED lighting surpassed CFL lighting
-25x + 6y = 20
15x + 2y = 322 (-3)
-25x + 6y = 20
<u>-45x - 6y = -966 </u>
-70x = -946
x = 13.51
The nearest year would be 14 which is 2014
Answer:
<h2><u><em>
60°</em></u></h2>
Step-by-step explanation:
it looks like an isosceles triangle, 2 equal side and 2 equal angles (F&E)
the sum of the interior angles in a triangle is 180°, and FH is 180°.
180 - 120 = 60° (angle G)
now we know that it is an equilateral triangle, so Y and 2x are 60°
(3 * 60 = 180°)
-------------------------------
or
180 - 60 = 120
120 : 2 = 60°
