So, the difference in temperature between the two cities is 15°C
Answer:
(-2, 6)
Step-by-step explanation:
you can use the substitution method:
(4, 7) Is 7 > 8 - 1? No, 7 is not greater than 7
(1, -4) Is -4 > 2 - 1? No, -4 is not greater than -1
(-2, 6) Is 6 > -4 - 1? Yes, 6 is greater than -5
(0, -8) Is -8 > -1? No
Step-by-step explanation:
we know about vertical angels that are equal
so <2=<4
(in fact they are congruent angles)
we found those only from the definition of vertical angles.
Answer:
10 years
Step-by-step explanation:
let they become of same height after t years
3ft=36 inches
hence
height of A
Ha=36+21t
8ft=96 inches
height of B
Hb = 96+15t
as Ha =Hb
36+21t =96+15t
21t-15t =96-36
6t=60
t=60/6
t= 10 years
