An expression is shown.
5 x 20 x 10²
what is the value of the expression?

10,000

Step-by-step explanation:

using PEMDAS we multiply the exponent first to get 5*20*100, now they are all multiplicative so we go left to right, 100*100 which is 10,000

Step-by-step explanation:

To find x:

We can use the angle sum property of a triangle which states that, The sum of all internal angles of a triangle is always equal to 180°.

Therefore,

Now that we know the value of we can use it to find the value of .

We can see that angle and are supplementary which means:

Now that we know the value of we can use the angle sum property of a triangle again:
