Answer:

I think there is a mistake in the choices because the sum of the angles of a circle 360°

So :

x+ 90°+ 100° + 60° = 360°

x+ 250° = 360°

x = 360° –250°

x= 110°

Just this that I know

good luck.

Is line AB tangent to the circle ?

galben [10]

Answer:

Yes

Step-by-step explanation:

A tangent has one point touching the circle and is always perpendicular to the radius drawn in as well. Therefore line AB is tangent to the circle and creates a right triangle.

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 :)

Suppose a triangle has two sides of length 33 and 37, and that the angle between these two sides is 120. What is the length of t

postnew [5]

Use the cosine law to answer the question which can be expressed as,
c² = a² + b² -2ab(cos C)
where c is the side opposite to angle C and a and b are the sides adjacent to the angle. Substituting the given values,
c² = 33² + 37² - (2)(33)(37)(cos 120°) = 3679
The value of c is 60.65. Therefore, the length of the third side is approximately 60.65 units.
