To solve this you will be needing to use PEMDAS! 
Parenthesis exponents multiply divide add subtract!
So first parenthesis...
609-78=531
So now we write the problem like this
10*80+531-10^2
Now exponents
10^2 is a exponent so that =10*10 which = 100
So we write it out again like this:  10*80+531-100
Now we need to multiply from left to write
So 10*80=800
Re-write it:
800+531-100
So now we need to add from left to write
800+531=1331
1331-100=1231
So your answer is 1231.
Does this help any?

The answer is:  " 60° " .
__________________________________________________________
     " m∠A = 60° " .
__________________________________________________________
Explanation:
__________________________________________________________

Note:  All triangles, by definition, have 3 (three) sides and 3 (three angles).

The triangle shown (in the "image attached") has three EQUAL side lengths.   Therefore, the triangle shown is an "equilateral triangle" and has 3 (three) equal angles, as well.

All triangles by, definition, have 3 (three) angles that add up to "180° " .

Since each of the 3 (three) angles is equal;  and the three angles are:  

  "∠A" , "∠B" , and "∠C" ;

We can find the measure of "∠A" ; denoted as:  "m∠A" ; as follows:
______________________________________________________
    m∠A  = 180° ÷ 3 = 60° .
______________________________________________________
The answer is:  " 60° " .
______________________________________________________
   m∠A = " 60° " .
