Answer:

∠COA = 160°

Step-by-step explanation:

The angle intercepted on opposite side of the circle from an ARC has a measure of HALF of the Arc.

∠CBA is HALF of the ARC CA

∠CBA is given as 80°

So Arc CA is 80 * 2 = 160°

Now,

∠COA is an intercepted angle that is at the CENTER. This angle has same measure as the Arc it is intercepted from (Arc CA).

Hence,

∠COA = Arc CA

<u>∠COA = 160°</u>

Summarize the possible relationships for the y -intercepts, slopes, and number of solutions in a system of two linear equations
ale4655 [162]

A consistent system of equations has at least one solution.

A consistent system is considered to be an independent system if it has a single solution, such as the example we just explored. The two lines have different slopes and intersect at one point in the plane.

A consistent system is considered to be a dependent system if the equations have the same slope and the same y-intercepts. In other words, the lines coincide so the equations represent the same line. Every point on the line represents a coordinate pair that satisfies the system. Thus, there are an infinite number of solutions.

Another type of system of linear equations is an inconsistent system, which is one in which the equations represent two parallel lines. The lines have the same slope and different y-intercepts. There are no points common to both lines; hence, there is no solution to the system.

What is the exact value of tangent (negative StartFraction pi Over 3 EndFraction)
ExtremeBDS [4]

Answer:

tan(-π/3) =  -1.732050808

Step-by-step explanation:

Given in the question, we have to find the value of tan(-pi/3) or it can be written as:

x = tan(-\frac{\pi}{3})

where x is the exact value of the given tangent.

However, in this question, one may get confused and put the value of π = 3.14, which is wrong. The value given is in radians, which is used to measure angles, just like degrees.

To make it easier, lets convert the radians into degrees. We know that

π = 180°

-π/3 = -180/3 = -60°

Find x:

x = tan (-60°)

x = -1.732050808

80+90=8+9 add a 0 to the end of your answer
Len [333]

Answer:

The answer is 170

Step-by-step explanation:

Because 8 + 9 = 17, if we multiply all of these values by ten or add a zero to the end of each number, we should get

80 + 90 = 170
