It is 1. 2 and 3 are base angles.
Answer:
For A = 32/5 and B = 8 the system of equations will have infinitely many solutions.
Step-by-step explanation:
Given equations are:
4x + 5y = 10
Ax + By = 16
The general form of linear equation in two variables is given by:
Here a, b and c are constants and x,y are variables.
In the given equations, after comparing with the general form
"In order for a system of equations to have infinity many solutions,
"
Putting the values we get
Hence,
For A = 32/5 and B = 8 the system of equations will have infinitely many solutions.
If 15 t-shirts were sold and 1/5 were grey,
then 4/5 of the shirts were white
Now, 4/5 of 15 = 12
∴ of the shirts sold, 12 were white
The two angle measures are equal (which is the point of an angle bisector), so you have
y + 30 = 3y - 50
30 = 2y - 50 . . . . . . . . subtract y
80 = 2y . . . . . . . . . . . . add 50
40 = y . . . . . . . . . . . . . .divide by the coefficient of y
The value of y is 40.
The three angles must add up to 180 degrees.
x - 39 + x - 29 + x = 180 Collect like terms on the left
3x - 68 = 180 Add 68 to both sides.
3x = 180 + 68
3x = 248
x = 248 / 3
x = 82.66667
Answer
x = 82,666667 for the largest angle
x - 29 = 53.666667 for the medium size angle
x - 39 = 43.666667 for the smallest size angle
