a) value of x:

ZX =(10x+9)°

122°=( 10x+9)

122 - 9= 10x

113= 10x

x = 113/10= 11.3 °

so answer is = 11.3°

b) measure of Arc XZ :

formula to find Arc= © angle÷360 x 2πr

A = 122÷360 x 2πr

A = 61/180x 2πr

A = 0.3388x2πr

A= 0.6776πr

Find the midpoint of the line segment whose endpoints are (2.6,5.1) and (3,4.7).

svp [43]

Answer:

Mid point is: (2.8;4.9)

Step-by-step explanation:

To find midpoint of a line segment we can use the general equation:

$Mid=\frac{x_1+x_2}{2} ;\frac{y_1+y_2}{2}$

Where the point of the line are: (x₁;y₁) and (x₂;y₂).

In the problem, x₁ = 2.6, y₁ = 5.1 and x₂ = 3 and y₂ = 4.7. Replacing in the equation:

$Mid=\frac{2.6+3}{2} ;\frac{5.1+4.7}{2}$

<h3>Mid point is: (2.8;4.9)</h3>
