Answer:
it is 4/3
Step-by-step explanation:
because tan(B) = opposite/adjacent
Plug your number
5(7) + 5^2/5
35+25/5
60/5

Answer:
± 13
Step-by-step explanation:
= ± 13, since
13 × 13 = 169 and - 13 × - 13 = 169
To eliminate x, the coefficients of x's in both equations should be opposite numbers. Since the coefficient of x in the second equation is 3, the coefficient in the first equation should be -3. So she should multiply the first equation by -3.
