Answer:
59 degrees
Step-by-step explanation:
Since angle BGC is 40 degrees and angle AGC is 19 degrees and they are asking for angle AGB which is the sum of both angles together, you just add the 40 degrees plus 19 degrees.
The only rule to follow is
Divide dividend by divisor and the mention the quotient and things left after remains in place of remainder
Here is a sample

Answer:
Step-by-step explanation:
4. f(x) = √(x + 4)
f(5) = √(5+4) = √(9) = 3
5. g(x) = x^12 - x^5
g(-1)= (-1)^12 - (-1)^5
1 - (-1) = 1 + 1 = 2
<span>x2 − 8x + 16
= (x - 4)(x - 4)
= (x - 4)^2</span>
