CAnswer:
Step-by-step explanation:
it is i got an 100
X - green marbles
X + 3 - blue marbles
Total = 23
X + X + 3 = 23
2X + 3 = 23
2X = 23 - 3
2X = 20
X = 10
Jerry has 10 green marbles. He also has 13 blue Marbles. To give a total of 23.
There is 180 degrees on a straight line so you can work out the unnamed angle in the triangle by doing 180-115 which is 65
There are also 180 degrees in a triangle so to work out y you do 180 - (65+85) = 30
So y = 30 degrees
