You will need to know that the sum of "two complementary angles" is 90 therefore Let x = one angle then 90-x = second angle . Now, we construct our equation based on the sentence: "The sum of the measures of two complementary angles exceeds the difference of their measures by 86°." x + 90-x = x-(90-x)+86 90 = x-90+x+86 90 = 2x-90+86 90 = 2x-4 94 = 2x 47 degrees = x (first angle) . Second angle: 90-x = 90-47 = 43 degrees (second angle) hope it helps
The price of the stock of PEV Corporation varies as shown. we have to determine the net charge. Net change is just how much it changed overall, so we will look for all the ups minus all the downs.
Here, "went up" goes with a + sign, and "went down" goes with a - sign.
