10. from the question; the circle theorem obeyed is "angled formed by semi-circle"

The angle formed in a semicircle is 90 degrees, hence

$m\angle XYZ=90^{\circ}$

This gives

$m\angle YXZ\text{ + m}\angle YZX\text{ = 90}$

But

$\begin{gathered} m\angle YXZ\text{ = 2x + 8} \\ m\angle YZX\text{ = 5X - 2} \end{gathered}$

Substituting values we get

$\begin{gathered} 2x\text{ + 8 + 5x - 2 = 90} \\ 2x\text{ + 5x + 8 - 2 = 90} \\ 7x\text{ + 6 = 90} \\ 7x\text{ = 90 -6} \\ 7x\text{ = 84} \\ \text{divide both sides by 7} \\ x\text{ = }\frac{84}{7} \\ x\text{ = 12} \end{gathered}$

hence, x =12

What’s the value of x?

son4ous [18]

180 - 53 - 96 = 31°. you know the angles are 53 and 96 degrees because the triangles are congruent via SAS congruency.

find the value of x show your work in the diagram below C is the midpoint of segment a b, a c equals 5x + 2 + CB equals 3x + 12

Dmitrij [34]

Answer:

Initial equation: 5x + 2 = 3x + 12

x = 5

Step-by-step explanation:

Point C is the midpoint between A and B.

This means that:

AC = CB

We have that:

AC = 5x + 2

CB = 3x + 12

Since AC = CB, the initial equation is:

5x + 2 = 3x + 12

Now we can solve

5x + 2 = 3x + 12

5x - 3x = 12 - 2

2x = 10

x = 10/2

x = 5
