Answer:
x=12
Step-by-step explanation:
To make these 2 lines perpendicular to each other, one of their angles must be equal to 90 degrees.
Therefore, we can set up an equation with one of the angles:
7x+6=90
7x=84
x=12
The information of the other angle is useless in this case, but we can use it to check by plugging in 12 for x, and seeing if it equals to 90:
8*12-6=96-6=90
Therefore, x=12.
Answer:
is an extraneous solution: True
is the only solution: True
Step-by-step explanation:
The given logarithmic equation is: 
Apply the property 
to the LHS to get: 
We rewrite the corresponding indicial expression to get:
Simplify the RHS to get:
Take square root to get:
Since the domain of the logarithmic function is positive real numbers, the only solution is
Answer:
BC = 19.78
Step-by-step explanation:
using sin(x) rule
sin(54)= 16/BC
sin(54)=0.80
∴0.80=16/BC (divied both side by 0.80)
BC=16/0.80 =19.78
