Answer:
-1 and 5
-2 and 6
-4 and 8
<u><em>They all give the same total i.e. 4</em></u>
1000 dived by 4 = 250 meters
250 x 2 = 500 meters
john ran 500 meters
∠GHJ and ∠RST are complementary
⇒ ∠GHJ and ∠RST = 90°
And ∠RST and ∠ABC are supplementary
⇒ ∠RST and ∠ABC = 180°
Also, ∠GHJ = x°
⇒ ∠RST = 90° - x°
⇒ ∠ABC = 180° - ∠RST
⇒ ∠ABC = 180° - (90° - x°)
⇒ ∠ABC = 90° + x°
Y=2x-5
Hope this helps ya :D
