Question

I need help solving A (ignore B and C, I have them solved already). I'm just a little confused on A​. I need to find the measure of X and Y

Answer 1

Answer:

x = -113

y = 30

Step-by-step explanation:

110+10+2y=180

2y=180-110-10

=60

y=60/2

y=60/2 =30

-3x-10-2x+15+110+120+95=540

-3x-2x =540+10-15-110-120-95

-5x=210

x=210/-5

x=210/-5 = - 42

Answer 2

Step-by-step explanation:

Here,

110+2y+10=180°(being sum of angles in

a straight line)

y=180-120

y=60°,,

now,

to find the value of X,

120+95+110+3x-10+2x+15=540°(being sum of all angle of pentagon)

330+5x=540°

5x=540-330

5x=210

X=210/5

x=42°,,
