Answer:
the answer is 15 degree
15
Step-by-step explanation:
first i looked at the numbers that weren't X and added up to 30° and subtracted that from 180 because a triangle equals 180. i got 150 and there is in total of 10 x's so i divided 150 by 10 and got 15! have a good day :)
y=2x+105
y/x =2/3
you just need see at one point. for example: (3, 2)
X=3
2(4x−3)−8=4+2x
2)(4x)+(2)(−3)+−8=4+2x
8x+−6+−8=4+2x
8x−14=2x+4
8x−14−2x=2x+4−2x
6x−14=4
6x−14+14=4+14
6x=18
x=3
