The value for the missing side is: 25. 4 5. None of these choices are correct.
andrew11 [14]

Answer:

5

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2

where a and be are the legs and c is the hypotenuse

3^2 + 4^2 = c^2

9+16 = c^2

25 = c^2

Take the square root of each side

sqrt(25) = sqrt(c^2)

5 =c

Find the given angle to the nearest degree.
Darina [25.2K]

Answer:

\alpha=44\°

Step-by-step explanation:

By definition, the tangent of an angle is the quotient between the side opposite the angle and the side adjacent to the angle

In other words:

tan(\alpha) = \frac{opposite}{adjacent}

In this triangle, the length of the side adjacent to the desired angle is 50, and the length of the opposite side is 48

So:

tan(\alpha) = \frac{48}{50}\\\\tan(\alpha)= 0.96

Finally

\alpha =arctan(0.96)\\\\\alpha=44\°

Let f(x)=−14(x+4)2−8 .
nevsk [136]
Answer:
Average rate of change = -112

Explanation:
The average rate of change = \frac{f(b) - f(a)}{b - a}
where:
b is the upper limit = 2
f(b) = f(2) = -14(2+4)² - 8 = -512
a is the lower limit = -2
f(a) = f(-2) = -14(-2+4)² - 8 = -64

Substitute with these values in the above equation to get the average rate of change as follows:
average rate of change = \frac{-512 - (-64)}{2 - (-2)} = -112

Hope this helps :)
