Step-by-step explanation:
35A) arc AC = 360-(100+110+80)=
360-290 = 70°
35B) <em>L</em><em> </em>D = ½× 70 = 35°
35C) <em>L</em><em> </em>AEC = ½(100+70)=½×170= 85°
35D) <em>L</em><em> </em>P = ½(100-70) = ½×30 = 15°
Answer: D) y= 14/17x - 4/17
Answer:
108°
Step-by-step explanation:
We know for a theorem that A = B, so:
4x + 28 = 2x + 68
Isolating the x:
2x = 40
x = 20
Now let's plug in the equation for A:
4(20) + 28 = 108°
Answer:
r = -1
Step-by-step explanation:
(y2-y1)/(x2-x1)=m
(r,7)=(x1,y1) and (3,4)=(x2-y2) and m=-3/5
so plug in...
(4-7)/(4-r)=-3/5
then solve for r which will get that r = -1
numerator: 4-7=-3
denominator: 4-r=5 -> 4-5=0+r -> -1=r
