Solve for x in the picture please.
SCORPION-xisa [38]

Answer:

X=20

Step-by-step explanation:

The 3 angles all add up to 180º because they are a straight line.

3x + 80 + 2x = 180

5x + 80 = 180

5x + (80-80) = 180-80

5x = 100

5x/5 = 100/5

X=20

Hope this helps!

I need some helppp people

We can observe that the function describing the graph is linear and so the equation is of linear nature:

y=mx+n

Numbers m and n have special names. m is called the slope, n is called y-intercept.

From the graph one can tell that the line intercepts y-axis at y = -1 that means n = -1. What about the slope you say?

The slope can be calculated using two points' coordinates that lie on the line:

m=\frac{\Delta y}{\Delta x}=\frac{-1-5}{0-5}=\frac{6}{5}

Now our line has an equation,

y=\frac{6}{5}x-1

Hope this helps.

Answer:

138

Step-by-step explanation:

Hey There!

So given that the opposite sides are equal to each other we know that angle RTU is equal to angle RTS so all we have to do is multiply 69 by 2

69x2=138 so angle STU = 138
