<span>multiply </span>40 by 7 wich equals 280 coins
Answer:
40, 60, 80
Step-by-step explanation:
The sum of angles in all triangles is 180 degrees (assuming you are talking about Euclidean geometry). If 2:3:4 is the ratio then
2x + 3x + 4x = 180
9x = 180
x = 20
Now that we now what x is, we can find the respective angles by plugging the value of x in. The angles are 40, 60, and 80 respectively.
Answer:
Assuming your equations are:
x-3y=3
4x+3y=-3
The answers are x = 0 and y = -1.
