Answer:
45°
Step-by-step explanation:
The angle with measure of 9x and the angle with measure of 3x are supplementary
9x + 3x = 180°
12x = 180 divide both sides by 12
x = 15
The angle with measure of 9x and angle a are supplementary as well
9x + a = 180
9×15 + a = 180
135 + a = 180 subtract 135 ftom both sides
a = 45°
(3,7) becomes (3,-7) when reflected across the x axis.

Complete Question:
The deck that Amos is building is in the shape of a parallelogram, DGRY. The measure of D is five-halves the measure of Y. Find the measure of each angle of the deck.
Answer:


Step-by-step explanation:
Given
Shape: Parallelogram DGRY
Dimension: 
Required
Find the measure of each angle
D and R are opposite sides & G and Y are also opposite sides.
So, we have:

and

The sum of angles is given as:

Substitute values for 

Take LCM


Multiply both sides by 





So:






Hence:

The solution to the problem is as follows:
Given: 2.5 lb
Asked: 2.5 lb -----> kg
Answer:
2.5 lb * ( 1 kg/2.2 lb) = 1.1 kg
Therefore, the weight of the book in kg is 1.1 kg.
