Answer:
since angle a and b are vertical angles
therefore we can say that,
i) <A=<B
or,20x+10=30x-10
or,10+10=30x-20x
or,20=10x
.°. x=10.
The slope of a line parallel to this line is -4/7
And the slope of a line perpendicular is 3/4
Linear, because the tank will eventually be empty. In about 10 weeks
6 ft
Step-by-step explanation:
We’ll use the trigonometric rule of SOHCAHTOA;
Well use <em>TOA</em> – since we know the value of the adjacent side and we are evaluating for the opposite side;
Tan Φ = Opposite / Adjacent
Tan 36 = x / 8
x = Tan 36 * 8
x = 5.81234
x = 6 ft
