Answer:
![C = 28.9](https://tex.z-dn.net/?f=%20C%20%3D%2028.9%20)
Step-by-step explanation:
Given the right angled triangle, ∆BCD, you are required to find the measure of angle C.
Apply the trigonometric ratio formula to find m < C.
Adjacent side = 7
Hypotenuse = 8
Trigonometric ratio formula to apply would be:
![cos(C) = \frac{7}{8}](https://tex.z-dn.net/?f=%20cos%28C%29%20%3D%20%5Cfrac%7B7%7D%7B8%7D%20)
![cos(C) = 0.875](https://tex.z-dn.net/?f=%20cos%28C%29%20%3D%200.875%20)
![C = cos^{-1}(0.875)](https://tex.z-dn.net/?f=%20C%20%3D%20cos%5E%7B-1%7D%280.875%29%20)
![C = 28.9](https://tex.z-dn.net/?f=%20C%20%3D%2028.9%20)

Answer:
B) (-∞,1)
Step-by-step explanation:
g(x)=-2f(x)+1
g(x)=-2(10^x)+1
Therefore, x can be any real number, but y can be any real number that's less than 1. This means B is correct.
Answer:
The form of hypothetical syllogism is;
If P, then Q.
If Q, then R.
Therefore, if P, then R.
From the given statement we have:
M represents "If a, b, and c are real numbers such that a=b",
N represents "a+c=b+c"
O represents "c+a=c+b".
we have;
If M, then N
If N, then O
Therefore, by hypothetical syllogism.
therefore, if M, then O.
Therefore, the statement completes the syllogism is:
If a+c=b+c, then c+a=c+b.
