Answer:
i need help my self
Step-by-step explanation:
Answer: C
Step-by-step explanation: c is the correct answer. A is incorrect, because 8 is subtracting t, so it is a higher value. B is incorrect because it’s 8/f so 8 is greater. (If it was f/8 then 8 would be less). C is correct because 8 is being taken away from f, not the other way around. And lastly, d is incorrect bc there’s no way to tell which is greater/less. Hope this helped ;)
Answer:
"You could add each number one by one in your head, and the total is your answer."
Answer:
m∠C = 90°
Step-by-step explanation:
Triangle BDC is a right triangle with the measure of angle D = 90°
By applying Cosine rule in the given triangle,
Since, Cosine of any angle in a right triangle is a ratio of Its adjacent side and Hypotenuse (Opposite side of the right angle)
CosC = 
CosC = 
CosC = 
C = 28.955
C = 29°
Therefore, m∠C = 29° will be the answer.
=(9(1/3))^2+2+4/7
=(3^2)+2+4/7
=(9)+2+4/7
=11+4/7
=81/7
