Answer:
The length of BC is 17 units
Step-by-step explanation:
we know that
An isosceles triangle has two equal sides and two equal angles
In this problem we have an isosceles triangle
Because
m∠ACB=m∠ABC ----> given problem
so
AC=AB
substitute the given values

solve for x


therefore
The length of BC is 17 units
This is the isosceles right triangle, the diagonal of a square, the thing that so upset the Pythagoreans. The two sides and diagonal of a square are in ratio
so we get

We could have also gotten this using Trig:


Or by recognizing u=v because remaining angle is 45 so this must be isosceles so



Answer:
The value of <em>n </em>is 15.
Step-by-step explanation:
The combined proportion is computed using the formula:

The information provided is as follows:

Compute the value of <em>n</em> as follows:


Thus, the value of <em>n </em>is 15.
We know that the form of line passing through point (x₀ , y₀) and having slope m is : y - y₀ = m(x - x₀)
Here the line passes through the point (-2 ,9)
x₀ = -2 and y₀ = 9 and Given : Slope(m) = -14
Equation of the line :
⇒ y - 9 = -14(x + 2)
