Just like you would if you had a normal number so times 1.5 times 3
Step-by-step explanation:
5x+23=0
5x=23
x=23-5
(x=7)
Answer:
77 degrees
Step-by-step explanation:
The interior angles of a triangle always add up to 180 degrees, so you can form an equation:


(3,-4) is your x and y. Plug it in the equation so,
For x,
2x+3y=3
2x+3(-4)=3
2x-12=3
2x=12+3
2x=15
2x/2=15/2
x=7.5
For y,
2(3)+3y=3
6+3y=3
3y=-6+3
3y=-3
3y/3=-3/3
y= -1
Answer: point of tangency
