Answer:
Point of tangency is or
Step-by-step explanation:
You don't really need to use Calculus here. You can just set each equation to each other and solve for x (the point of tangency):
Therefore, the point of tangency is or
Answer:
12/11
Step-by-step explanation:
the formula to find the slope of a line is:
where is the slope and and are the points where the line passes.
in this case we have that the first point is: (25,50) thus⇒ and
and the second point: (80,110) thus ⇒ and
substituting this values into the formula for the slope:
the slope of the line is 12/11
Rewrite as (2^1/2 + 2^1/2)*(18^1/2-2^1/2) = 8
supplementary angles are 180°
<1+<2=180°
given that <1=112°
112°+<2=180°
<2=180°-112°
<2=68°
