Answer:

3 vases chipped.

Step-by-step explanation:

Let's use a ratio:

chipped : all

2 : 12

1 : 6

3 : 18

We can expect 3 out of 18 vases to be chipped.

Given:

In $\Delta QRS, \overline{QR}\cong \overline{SQ}$ and $m\angle Q=114^\circ$ .

To find:

The $m\angle S$ .

Solution:

In $\Delta QRS$ ,

$\overline{QR}\cong \overline{SQ}$

It means the triangle QRS is an isosceles triangle. We know that the base angles of an isosceles triangle are congruent and their measures are equal.

$\angle R\cong \angle S$ [Base angles of isosceles triangle QRS]

$m\angle R=m\angle S$ ...(i)

In $\Delta QRS$ ,

$m\angle Q+m\angle R+m\angle S=180^\circ$

$m\angle Q+m\angle S+m\angle S=180^\circ$ [Using (i)]

$114^\circ+2m\angle S=180^\circ$

$2m\angle S=180^\circ-114^\circ$

$2m\angle S=66^\circ$

Divide both sides by 2.

$m\angle S=\dfrac{66^\circ}{2}$

$m\angle S=33^\circ$

Therefore, the $m\angle S$ is 33 degrees.

nadezda [96]

The value of x is 54 and the measure of angle 8 is 64 degrees

<h3>How to determine the value of x and find the measure of angle 8?</h3>

The given parameters are

Angle 1 = 2x + 10

Angle 8 = x + 10

The figure that completes the question is added as an attachment

From the figure, we have

Angle 1 = Angle 3 ---- vertical angles

Angle 3 + Angle 8 = 180 ---- internal angles within the transversal

Substitute Angle 1 = Angle 3 in the equation Angle 3 + Angle 8 = 180

Angle 1 + Angle 8 = 180

Substitute the known values in the above equation

2x + 8 + x + 10 = 180

Evaluate the like terms

3x = 162

Divide both sides by 3

x = 54

Substitute x = 54 in Angle 8 = x + 10

Angle 8 = 54 + 10

Evaluate

Angle 8 = 64

Hence, the value of x is 54 and the measure of angle 8 is 64 degrees
