3. triangle abc has angle measures as shown.
(a) what is the value of x? show your work.
(b) what is the measure of angle c? show your work.

angle a = 38 degrees
angle b = x
angle c = x + 2

Value of X= 70

Angle measure of C is 72 degrees

Ok, so this is how I got it

Although this is geometry, you have to use some pre-algebra.

Every single triangles angle measures adds up to 180 degrees.

In order to find X, the equation is:

m of angle a + m of angle b + m of angle c= 180

Plug in your numbers

38 + X + X + 2 = 180

Add your like terms,

X + X= 2x and 38 + 2= 40

Now our eq looks like this: 2x + 40 = 180

This is where the pre algebra comes in

Subtract 40 from both sides because the opposite of adding 40 is subtracting 40

40 - 40= 0 and 180 - 40 = 140

Now our eq looks like: 2x = 140

Since 2 and X are being multiplied we do the opposite which is divide 2 and 140

140 divided by 2= 7-0

X = 70

Now you know the value of x, so just plug it in.

38 + 70 + 72 = 180??

If it equals 180 you are correct (it does )

I am so sorry it is long and if it is confusing I am sorry too, but it is kind of hard to explain thru typing, but I hope it helps in some way :)

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.  

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
