Mathematics

The sum of all the angles in a pentagon is 540 degrees.
To solve for x, you must add up all the known angles and then subtract from 540.

So, you. Would do, 540-(100+100+90+120)

That equals 540-510 which is 30.

Your final answer is x=30

Hope it helps!!

Answer:

Step-by-step explanation:

(–5g^5 h^6)^2 × (g^4 h^2)^4        the ^ carot symbol means raised to power X

 (25 g^10 h^12) × (g^16 h^8)         exponents raised to powers MULTIPLY

  -5² = 25   g^5² = g^10  h^6² = h^12     do the same thing with   (g^4 h^2)^4

  25 g^(10+16) h^(12+8)                 collecting terms powers ADD

  25 g^26 h^20                         Which letter is the answer?  

                                                  Did you follow my explaination?
