Answer:
Step-by-step explanation:
This triangle is a polygon. By definition, all the exterior angles of ANY polygon add up to equal 360 degrees. So we add up all the exterior angles and solve for x. That's the first step.
7x - 2 + 9x - 31 + 4x + 33 = 360
Combining like terms gives us
20x + 0 = 360 or simply
20x = 360 so
x = 18
In order to find the value of the angle exterior to angle C, we sub 18 in for x:
7(18) - 2 = 124
S= Sydney
devaughn= s-13
so s+s-13=75
2s-13=75
now I think you can solve the rest.
22 need more
150-56=94
20*3 = 60
94-60 = 34
34-12= 22
Answer:
a= 6
b= -12
Step-by-step explanation:
In complex number algebra, you need to sum the real values with each others and the imaginary values with each others.
In order to determine which number is a real value and which one is an imaginary, we must expand the parenthesis terms:

Now we match real numbers with real numbers and imaginary numbers with imaginary numbers:

The points that are possible approximations for this system are; (2.2, -1.4) and (2.2, -1.35)
<h3>How to find the solution of a linear graph?</h3>
We are given the equations of the linear graphs as;
y = ⁷/₄x + ⁵/₂
y = ³/₄x - 3
Notice that the lines intersect each other and by definition, if the lines of the system of equations intersect, then the system has one solution. This means that the point of intersection of the lines is the solution of the system. It can be written as:
(x, y)
x is the x-coordinate .
y is the y-coordinate.
In this case, we can identify that:
- the x-coordinate of the point of intersection is between; x = 2 and x = 3
- The y-coordinate of the point of intersection is between y = -1 and y = -2
Based on the above, we can conclude that the points that are possible approximations for this system are; (2.2, -1.4) and (2.2, -1.35)
