Answer:
Step-by-step explanation:
A triangular prism has a triangular base. Finding a triangle's area requires two known quantities: base, labeled b, and height, labeled h. Base is the length of one of the triangle's sides, height is the distance from that side to the opposite corner of the triangle.
You can set them equal to eachother
x+1=3x-19
solve for X
-3x both sides
-2x+1=-19
-1 both sides
-2x=-20
÷-2 both sides
x=10
y=10+1
y=11
answer
he is simple following addition rule
