Answer:
∠ 1 = 65°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
5x - 10 is an exterior angle of the triangle, then
5x - 10 = 3x + 40 ( subtract 3x from both sides )
2x - 10 = 40 ( add 10 to both sides )
2x = 50 ( divide both sides by 2 )
x = 25
The sum of the 3 angles in a triangle = 180° , so
∠ 1 + 40 + 3x = 180°
∠ 1 + 40° + 3(25) = 180°
∠ 1 + 40° + 75° = 180°
∠ 1 + 115° = 180° ( subtract 115° from both sides )
∠ 1 = 65°
NO!
1 yd=3 ft
36*3=108
108+2=110
114>110, therefore no
<u>ANSWER: </u>
The slope of the given line y - 3 = (x - 5) is 1 and (5, 3) is a point on that line.
<u>SOLUTION:
</u>
Given, line equation is y – 3 = (x – 5)
We have to find the slope of the given equation along with a point on that line.
Now, if we observe, the given equation is in point slope form 
Where, m is the slope of the line and
is a point on the line.
Now by comparison of the two equations we can conclude that,

So, the point on the given line is (5, 3).
Hence, the slope of the given line is 1 and (5, 3) is a point on that line.
