Answer:
x = 17.3238
Step-by-step explanation:
Tan Ф = 34/x
cross multiply,
x = 34×Tan Ф
but, Ф = 27°
so that, x =34 × Tan 27°
x = 17.3238
Answer:
(3,7) is not a solution
Step-by-step explanation:
You fill in the values x=3 and y=7 in both equations and see if you end up with something that is true.
-5·3 - 2·7 = 23 is not true, because it simplifies to -29 = 23
no need to look further, but if you would, the second equation is also false:
3 + 4·7 = -19 is also not true.
The real solution by the way is (-3, -4).
