Can someone find the value of the largest interior angle?

The 130° angle is supplementary with its adjacent angle (see attachment). Supplementary angles add to equal 180 degrees; you can find the measure of the interior angle by subtracting the measure of the exterior angle from 180.

180 - 130 = 50

Now that you have values for all interior angles, you can set them equal to 180, since the interior angles of all triangles add to equal 180 degrees. Find x.

180 = (3x + 5) + 2x + 50

180 = 3x + 5 + 2x + 50

180 = 5x + 55

125 = 5x

25 = x

To find the largest interior angle, substitute 5 for x and solve.

3x + 5 --> 3(25) + 5 --> 75 + 5 --> 80

2x --> 2(25) --> 50

The third interior angle measure is 50°.

80°

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
