The base angles of isosceles triangles are congruent therefore Angle c also measures 4x+6. add all 3 angles of any triangle you always get 180

3x+47 + 4x+6 + 4x+6=180
11x=121
x=11 the three angles measure 80, 50, and 50

Answer:

D

Step-by-step explanation:

Here, we want to get the equation of the line perpendicular to;

y = -3x + 2

From here, we can compare with the standard form of the equation of a straight line which is;

y = mx + c

From here m = -3

The slope is -3

Now, if two lines are perpendicular, the product of their slopes is -1

Thus;

-3 * m = -1

m = 1/3

So we want to select an equation out of the options that has a slope of 1/3

Let us take a look at the last option

x -3y = 3

3y = x-3

divide through by 3

y = x/3-1

So here the coefficient of x is 1/3 which is the slope of the perpendicular line that we are looking for and is our slope

A football team won 8 more games than they lost. They played 24 games in the season. How many games were won and how many were l
Vaselesa [24]

The team lost n games.

The team won 8 more games than it lost, so it won n + 8.

The total number of games the team played was n + n + 8, or 2n + 8.

The team played a total of 24 games, so

2n + 8 = 24

We now solve for n.

2n + 8 = 24

2n = 16

n = 8 (lost games)

n + 8 = 8 + 8 = 16 (won games)

Answer: The team won 16 games and lost 8 games.
