Answer:
70° is the answer hope it helps
30°+90°+ 3y= 180°
120°+3y= 180°
3y= 180°-120°
y= 60°/3
y= 20°
Now
y°+90°+x°= 180°
20°+90°+x= 180°
x= 180°-110°
x= 70°
Decrease because you taking something off of something
(2x-3)(x+4) —> x= 3/2 x= -4
This is something to memorize
y = r*sin(theta)
so if y = 2, then
2 = r*sin(theta)
Divide both sides by sin(theta) to get
r = 2/sin(theta)
r = 2csc(theta)
