Answer:

x=35°

Step-by-step explanation:

So first, recall that the interior angles of a triangle must total 180°.

The sum of the angles for the given triangle can be described by:

110+x+x\\=2x+110

Since the total must equal 180°, set the expression equal to 180°.

2x+110=180

To find the value of x, we just need to solve for x.

To start, subtract 110 from both sides. The 110s on the left cancels:

(2x+110)-110=(180)-110\\2x=70

Now, divide both sides by 2. The 2s on the left cancel.

\frac{(2x)}{2}=\frac{(70)}{2}\\ x=35 \textdegree

Therefore, the value of x is 35°.

YM is a median of the triangle below. XM = 2x + 2 and ZM = 4x - 8. What 5 points
LenaWriter [7]

Answer:

Option A: 12

Step-by-step explanation:

From the image of the triangle given, we can see that:

XM = ZM

We are given that:

XM = 2x + 2 and ZM = 4x - 8

Thus;

2x + 2 = 4x - 8

Rearrange to get;

4x - 2x = 8 + 2

2x = 10

x = 10/2

x = 5

Thus, XM = 2(5) + 2

XM = 12
