Answer:
z = 60
Step-by-step explanation:
100+20+z=180
120+z=180
z=60
1. A=(0,4)
2. B=(4,1)
3. Slope=-3/4
Answer:
y = 1/7x + 88/7
Step-by-step explanation:
y = mx +b
since it is perpendicular you have to get the negative reciprocal of the slope which is 1/7
y = 1/7x + b then you would plug in your points
12 = 1/7(-4) + b and then solve for b
12 = -4/7 + b
+ 4/7
88/7 = b
y = 1/7x + 88/7
That would be 3.5 b/c it can’t be expressed as a ratio or a simple fraction
