Find the value of x in the Triangle shown below x=?​

Mathematics
1 answer:
NNADVOKAT [17]3 years ago
3 0

Answer:

x = 66°

Step-by-step explanation:

unmarked angle = x because it is an isosceles triangle.

The sum of all three interior angles of any triangle = 180°

So:

2x + 58° = 180°

2x = 122°

x = 66°

Solve the system using substitution.
miv72 [106K]

Substitution method is one of the ways to solve this system.

-5x+y=4 and 4x-4y=16.

First we will divide the second equation with number 4 and get

x-y=4 => x=y+4 than we will replace x in the first equation

-5(y+4)+y=4 => -5y-20+y=4 => -4y=4+20 => -4y=24 => y=-6

x-(-6))=4 => x+6=4 => x=4-6=-2    (x,y)=(-2,-6)

Good luck!!!

Evaluate
lakkis [162]

A piece-wise function combines more than one functions of different input values.

<em>The value of f(-1) is -3</em>

From the graph, we have the following observations

  • <em>When x = -1, y = -3</em>
  • <em>When x = -1, y = -4</em>

Notice that there is a closed circle at the point where x = -1 and y = -3.

This means that y = -3 is inclusive of the values of y on that particular function

However, there is an open circle at the point where x = -1 and y = -3.

This means that y = -4 is exclusive of the values of y on that particular function

The correct corresponding value of y is when y is inclusive.

Hence, the value of f(-1) is -3

See attachment for the graph of the piece-wise functions
