Answer:
Step-by-step explanation:
Sin(A) = a/c
Cos(A) = b/c
Tan(A) = a/b
49-30-1= 18
7 to the second power is 49
3 times 2 is 6; 6 times 5 is 30
and then subtract regularly
Answer:
y = 9/2x -9
Step-by-step explanation:
it's kind of hard to see but it looks like the line intersects the y axis at -9. then using two points on the line, (2,0) and (0, -9) you can find the slope with the equation
m= y2-y1/x2-x1 or m = -9-0/0-2 = -9/-2 = 9/2
