Set it up in an equation.
1) 45+5x=9x+9
2) Get x on ONE side: subtract 5x from both sides
3) bring down the equation: 45=4x+9
4) get x by itself: subtract 9 from both sides
5) bring down the equation: 36=4x
6) get x by itself: divide 4 from both sides
7) bring down the equation : 9=x
8) put 9 in the place of x : 9(9)+9
9) 9•9=81
10) 81+9=90
So the exterior angle is equal to 90.
For this case we must simplify the following expression:
We apply distributive property:
To multiply powers of the same base, the same base is placed and the exponents are added.
We simplify similar terms:
Finally we have:
Answer:

Step-by-step explanation:
Not sure what the clear dot means, but the following is always true:
h(k(any number, let’s say N))=N.
The express is in the pic but the answer is 1.257 radians
