20 points brainlist thanks please help Part B: Explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal. (5 points)

<x = 53 degrees

Step-by-step explanation:

<Q = 62 degrees (alternate angle)

<PRQ = 180-115 (Angles on a straight line add up to 180 degrees)

<PRQ = 65 degrees

Now, Finding <x

To find <x, we'll simply subtract 180 from rest of the triangles interior angles because the interior angles of a triangle add up to 180 degrees

=> <x = 180-65-62

=> <x = 53 degrees

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
