X = 57. Use the rules for inscribed angles. If that exterior angle is 123, then its supplement is 57. That 57 degree inscribed angle has an intercepted arc that is also the same arc that angle x intercepts. So x has the same measure as the other inscribed angle. Your answer is B.
Answer:
cotΘ = 
Step-by-step explanation:
Using the trigonometric identity
cot x = 
, then
tanΘ = 
= 
, hence
cotΘ = 
=
Answer:
34
56/19
6
Step-by-step explanation:
∵ z = 8
∴ 4(8) + 8 - 6 =34
∵ x = 3
∴ 7z /(4 + 5x) = 7(8) ÷ (4 + 5 × 3) = 56 ÷ 19 = 56/19
∵ y = 12
∴ y² ÷ 3z = (12)² ÷ 3(8) = 144 ÷ 24 = 6
Answer: im almost positive its -1 1/2
Step-by-step explanation:
Answer:
3x - 7
Step-by-step explanation:
x - (-2x + 7)
x + 2x - 7
= 3x - 7
