M 2 = 2x°, m 3 = 5x°, m 1 =<br><br> 2x + 5x<br> 5x - 2x<br> 180 - 5x<br> 180 - 7x
MaRussiya [10]

We know: the sum of measures of triangle angles is 180°.

Therefore we have the equation

m\angle1+m\angle2+m\angle3=180^o\to m\angle1=180^o-m\angle2-m\angle3

Substitute m\angle2=2x,\ m\angle3=5x:

m\angle1=180-2x-5x=180-7x

<h3>Answer: 180 - 7x</h3>

The measures of two angles of a triangle are 35 degrees and 45 degrees what is the measure of the third angle of the triangle?
sineoko [7]
Let the third angle = x
It would be: 35 + 45 + x = 180
80 + x = 180
x = 180 - 80
x = 100

So, your final answer is 100

Hope this helps!

What is the equation of the line containing the points (-1,3) and (2,9)
Paul [167]

Answer:

y = 2x + 5

Step-by-step explanation:

First,

9-3 = 6

over

2-(-1) = 3  

Then,

6 divided by 3 = 2

2 = slope

Next, using (-1,3), *you can use either ordered pair

y - 3 = 2 {x - (-1)}

y - 3 = 2x + 2

y = 2x + 5
