Answer: Below
Step-by-step explanation:
Let's start with 12. Going off of basic quadrilateral rules, adjacent angles will be equal to 180. So we make the equation:
8x - 12 + 3x + 5 = 180
Simply.
11x - 7 = 180
11x = 187
x = 17
Since R = P, R = 3(17) + 5 = 56
Now with 14.
We know ABC is both 115 and 4x+6, so:
115 = 4x + 6
109 = 4x
x = 27.25
ADB is 6x - 11, so 6(27.5) - 11 = 152.5
12) 56
14) 152.5
