The measures of the angles of a triangle are shown in the figure below. Find the measure of the smallest angle.

Answer:

(2x+18) degrees

Step-by-step explanation:

A triangle is a total of 180 degrees, so you would do:

(2x+18)+55+(4x+11)=180

(2x+4x)+(18+55+11)=180 <- take out parentheses and add like terms

6x+84=180 <- subtract 84 from both sides of the equation

6x=96 <- divide 6 from each side

x=16

Now that you know what x is you would plug it into each of the angles

Angle 1: 2x+18 --> 2(16)+18= 32+18= 50

Angle 2: 55

Angle 3: 4x+11 --> 4(16)+18= 64+18= 82

Then out of these three angles of the triangle, angle 1 (2x+18) would be the smallest.

The given equation is in point-slope form.

The general form of an equation in point slope form is:

$y- y_{1}=m(x- x_{1})$

Here m is the slope and $x_{1}$ and $y_{1}$ are the coordinates of the point.

So in given equation the slope is 2/3, and the coordinates of point are (1,3)
