(-9,-2) (1,3)
slope = (3 - (-2) / (1 - (-9) = 5/10 = 1/2
y - y1 = m(x - x1)
slope(m) = 1/2
(1,3)...x1 = 1 and y1 = 3
sub
y - 3 = 1/2(x - 1)
y - 3 = 1/2x - 1/2
y = 1/2x - 1/2 + 3
y = 1/2x - 1/2 + 6/2
y = 1/2x + 5/2 <=== slope intercept form
Answer:
34
Step-by-step explanation:
Straight lines are 180 degrees, so the angle inside of the triangle next to the 127, is 53 degrees. (180-127= 53)
So to find "x", we need to figure out what the full number is.
59+53 = 112.
180-112= 68.
Now that we have the degree of the full angle, we can make an equation to find x.
x*2 = 68
(Divide 2 from both sides to isolate the variable)
x = 34
I hope this helped!
I’d say but it in one box because it is a prime number.
Answer:
Well, 100 km equals approximately 63 miles.
Step-by-step explanation:
One mile is approximately 1.6 km, so you just divide 100 km by 1.6 and you should get the miles, being 62.5 miles, or 63.
First we add all the angles together
x + 2x - 20 + 2x + 10 = 5x - 10
Now, you should know that all the angles in a triangle add up to 180°
180 = 5x - 10
Move the 10 to the other side
190 = 5x
Divide both sides by 5
x = 38
So the angles sizes in ascending order are
38 , 46 , 86
