x = 6
The average of 4 numbers is 6, which means that (3 + 5 + 10 + x) all divided by 4 is 6. That means that 3 + 5 + 10 + x = 24, because 24/4 is 6.
18 + x = 24, subtract 18 from 24 to get x = 6.
Math is used in construction everywhere.Math is used in construction to measure parts, how many feet, inches, etc. to do and how high to go up.A great example is in the scaling of blueprints, where an architect creates a scale model of the building so that it can fit on paper.
Answer:
The relation is 
Step-by-step explanation:
x and y are directly proportional:
This means that the equation is given by:

In which a is the multiplier that relates these two variables.
x= -4, y =6
We use this to find a. So




So
The relation is 
we know that
The measure of the interior angle is the half-summit of the arcs that comprise it and its opposite
so

therefore
the answer is
the measure of arc TU is equal to
