We know that the sum of all the exterior angles will add up to 360°.
We can solve this using an expression:
360/n
n = the number of sides (in the problem, we are given 19 sides)
Solve with the given value:
360/19
18.947368
Round to the nearest tenth:
18.947368 → 18.9
Therefore, the answer is 18.9
Best of Luck!
Answer:
2+x
Step-by-step explanation:
Sum= addition
If the number is not provided we always include a variable and the most common one is X never use t, o, i, l, because you might confuse yourself because they look like numbers when they are variables.
Answer: c.41.31
Step-by-step explanation:
Answer:
81
Explanation:
[(2^2) (3^4) (12^3)]/[(2^5) (6^3)]
Whenever you have a number that can be separated into parts you can and give the same exponent:
[(2^2) (3^4) (2^3x2^3x3^3)]/[(2^5)(2^3x3^3)]
Whenever you multiply two terms with the same base, you can add the exponents:
=[(2^8)(3^7)]/[(2^8)(3^3)]
Take both 2^8’s out
=(3^7)/(3^3)
Whenever you have two exponents with the same base divided you just subtract the exponents:
=3^4
=81
The answer is 81
5x - 4 -9x + 7
simplify
5x - 9x = -4x
-4 + 7 = 3
Answer: -4x - 3
