Two straight lengths of wire are placed on the ground, forming vertical angles. If the measure
nikdorinn [45]

Answer:  72°, 108°, 108°

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

Vertical angles are congruent (equal) so if one angle is 72° then its vertical angle is also 72°.

A vertical angle and its adjacent angle form a 180° angle, so the other two angles are each 180° - 72° = 108°

Determine the value of x. <br>Do,k (x, 9) (-10, -6) A. 5 B. 7 C. 12 D. 15​
katen-ka-za [31]

The value of x in D o,k (x,9) -> (-10,-6) is (d) 15

<h3>How to determine the value of x?</h3>

The dilation rule is given as:

D o,k (x,9) -> (-10,-6)

Write out the coordinates

(x,9) -> (-10,-6)

Express as fraction

x/9 = -10/-6

Multiply both sides by 9

x = -9 * 10/-6

Evaluate the product

x = 15

Hence, the value of x in D o,k (x,9) -> (-10,-6) is (d) 15
