Mathematics
1 answer:
ahrayia [7]3 years ago
6 0

Step-by-step explanation:

To find x,

21x - 9 = 117

21x = 126

x = 6

To find arc AB,

21(6) - 9 = 117

To find Arc AE,

117 + x = 180

x = 63

Arc ABC,

117 + 63 = 180

ACE

180 + 27 + 90 = 297

Simplify n^6 × n^5 × n^4 ÷ n^2 ÷ n<br>PLEASE ANSWER ASAPPP!!! Will get BRAINLIEST****​
babymother [125]

Answer:

n¹³

Step-by-step explanation:

Division and multiplication have the same priority in pemdas, so you can solve this by dividing/multiplying from left to right.

Also remember that when dividing exponents of the same base, you subtract them, and when multiplying, you add them.

n⁶· n⁵ · n⁴ ÷ n³ · n² ÷ n

= (n⁶· n⁵) · n⁴ ÷ n³ · n² ÷ n

= (n¹¹ · n⁴) ÷ n³ · n² ÷ n

= (n¹⁵ ÷ n³) · n² ÷ n

= (n¹² · n²) ÷ n

= n¹⁴ ÷ n

= n¹³

Ultimately you just have to calculate

6 + 5 + 4 - 3 + 2 - 1 = 13

Answer:

She is not correct because ∠1 is an alternate exterior angle with ∠3, not the angle that measures 105°. So m∠1 = 75°.
