The three angles of a triangle are represented by the expressions

Mathematics

I'm guessing that the two expressions are for separate equilateral triangles.

If so, the equations would be:

3(3x-14)=180
3(x+4)=180

to solve the first equation, divide by 3:
3x-14=60
then, add 14 to both sides:
3x=74
lastly, divide both sides by 3:
x=24.667

to solve the second equation, divide both sides by 3:
x+4=60
then, subtract 4 from both sides:
x=56

Proving That All Circles Are Similar
Nitella [24]

Answer:

Figures can be proven similar if one, or more, similarity transformations (reflections, translations, rotations, dilations) can be found that map one figure onto another. In our attempt to prove all circles are similar, a translation and a scale factor (from a dilation) will be found to map one circle onto another.

Answer:

  y = -4x +2

Step-by-step explanation:

The equation you're writing is in slope-intercept form. The coefficient of x is the slope, which is the "rise"/"run" of the line.

Here, to get from the left point to the right point, you must go down 4 units (rise=-4) and 1 unit to the right (run=1). So, the slope is ...

  m = rise/run = -4/1 = -4

The constant in the equation is the y-intercept: the y-coordinate of the point where the line crosses the y-axis. That point is marked as (0, 2), so its y-coordinate is 2.

The equation for the line is ...

  y = -4x +2
