**Step-by-step explanation:**

**Answer:**

x = 20, so the labeled angles are 80° and 100°.

**Step-by-step explanation:**

So the labeled angles measure 80° and 100°.

**The magnitude of the vector from the origin is 10**

**The unit vector in of the vector from the origin as (8/10, -6/10**

<u>**Step-by-step explanation:**</u>

<u>**1.Finding the magnitude,**</u>

we have the formula,

**magnitude=√a²+b²**

we have the values as a=8 and b=-6

Finding the magnitude we get,

magnitude=√a²+b²

**magnitude=√8²+6²**

magnitude=√100

**magnitude=10**

The magnitude of the vector from the origin is 10

<u>**2.Finding the unit vector**</u>

**Divide by the magnitude**

**Unit vector: (8/10, -6/10)**

**The unit vector in of the vector from the origin as (8/10, -6/10**

**Answer:**

x = 10

**Step-by-step explanation:**

Since M is at the midpoint of TL , then

TM = ML , substitute values

2x + 8 = 3x - 2 ( subtract 2x from both sides )

8 = x - 2 ( add 2 to both sides )

10 = x , that is x = 10
