Use the diagram to find the angle measures of the triangle. Recall that the sum of the angle measures of a triangle is 180 degre

My name is Ann [436]

Answer:

x =29

x+6 =35

4x = 116

Step-by-step explanation:

The sum of the angles of a triangle is 180

x+ (4x) + (x+6) = 180

Combine like terms

6x+6 = 180

Subtract 6 from each side

6x+6-6 = 180-8

6x = 174

Divide each side by 6

6x/6 = 174/6

x =29

x+6 = 29+6 = 35

4x = 29*4 =116

What’s the slope of the line that passes through 5,10 and 7,12

Marrrta [24]

Slope of the line passes through (5,10) and (7,12) is 1.

Step-by-step explanation:

Given,

The two points are (5,10) and (7,12).

To find the slope passing through the given points.

Formula

The slope of the line passing through ( $x_{1} ,y_{1}$ ) and ( $x_{2} ,y_{2}$ ) is $\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

Now, putting $x_{1} =5,y_{1}=10, x_{2}=7, y_{2} =12$ we get,

Slope = $\frac{12-10}{7-5}$ = $\frac{2}{2}$ = 1

Hence,

Slope of the line passes through (5,10) and (7,12) is 1.
