Answer:

Step-by-step explanation:
By definition, the sum of the interior angles of a triangle is 180 degrees.
You can observe that the given triangle has an angle that measures 90 degrees and it also has two equal sides.This means that the other two angles are equal.
Knowing this, you can conclude that the triangle is an Isosceles Right Triangle and the other angles measure 45 degrees each.
Therefore, now you know that:

Solving for "x", you get that its value is:

And for the other angle:

Solving for "y", you get that its value is the following:

Answer:
48 km.
Step-by-step explanation:
Multiply 6 and 8, you get 48.
Answer:

Step-by-step explanation:
Given

Required
Solve for x

Change base of 16 and base of 4 to base 2

Express 16 and 4 as 2^4 and 2^2 respectively

The above can be rewritten as:


So, we have:


Multiply through by 4



Divide through by 7


Apply the following law of logarithm:
<em>If </em>
<em> </em><em>Then </em>
<em></em>
So, we have:
