The flag of a country contains an isoceles triangle. (recall that an isoceles triangle contains two angles with the same measure) if the measure of the third angle is 15 degrees more than three times the measure of either of the other two angles, find the measure of each angle of the triangle. (recall that the sum if the measure of the angles of a triangle is 180 degrees)

angles: 33, 33, 114

Step-by-step explanation:

An isosceles triangle has 2 angles with the same measure x

the third angle = 15+3x

the 3 angles of a triangle = 180

x+ x + 3x+15 = 180

combine like terms

5x + 15 = 180

subtract 15 from each side

5x+15-15 = 180 - 15

5x = 165

divide by 5

5x/5 = 165/5

x = 33

two angles measure 33

the third angle = 3x+15

                        = 3*33 + 15 = 99+15 = 114

y=mx+b is the final answer!   : )

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
