Answer:
u = 156.25
Step-by-step explanation:
Step 1: Write equation
31.25 = u/5
Step 2: Solve for <em>u</em>
- Multiply both sides by 5: 156.25 = u
- Rewrite: u = 156.25
Step 3: Check
<em>Plug in u to verify it's a solution.</em>
31.25 = 156.25/5
31.25 = 31.25
Answer:
Hey,
Let A be (-1,7)
Let B be (5,1)
In order to find the distance we need to do
Once we plug x2=5 and x1=-1
and y2=1 and y1= 7
You get
Now to find the midpoint:
Using the same values defined above we get:
(2,4)

We know that the triangle is made up of 180°
To find "x" we need to know the two angles of the triangle.
We also know that the supplementary angles are made of 180°
In this case the supplementary angle would the angle were 100° and the missing value is.
Since supplementary angles are made of 180°
180°-100° = 80°
Now we know the two angles of the triangle.
Since the triangle is made up of 180°
180° = x + 70° + 80°
x + 150° = 180°
x = 180° - 150°
x = 30°
