Answer:
A = 125º
Step-by-step explanation:
Missing angle is the supplement of 157.5
180 - 157.5 = 22.5
----------------------------
Sum of angles in triangle is 180
22.5 + (-10x) + (-x + 20) = 180
Combine like terms
-11x + 42.5 = 180
Subtract 42.5 from both sides
-11x = 137.5
Divide both sides by -11
x = -12.5
---------------------------
A = -10(-12.5)
A = 125º
Answer:
Y=-1; y+1=0(x+4)
Step-by-step explanation:
Point slope form: y-y1=m(x-x1)
A horizontal line has a slope of "0" therefore our "m" value is 0
So
y+1=0(x+4)
Y+1=0x+0
y=-1
Hope this helps!
<span>7x+6y=30
6y = -7x + 30
y = -7/6x + 5
answer:
slope = -7/6</span>
