Answer:
Step-by-step explanation:
cosine law
a²=b²+c²-2(bc)cos44 (c=20, b=15)
a²=15²+20²-2(15*20)cos44
a=√15²+20²-2(15*20)cos44
a=13.91
Answer:
a=148.50
b=0.045
c=8

i just took the quiz on edgeunity
Answer:
-3/4, -2/5, -4/15
Step-by-step explanation:
using calculator, -3/4 = -0.75, -4/15 = -0.266666..., -2/5 = -0.40
imagine that -0.75, -0.26... and -0.40 are temperatures
the coolest temperature is -0.75, the warmest one is -0.26...
so the least number is -0.75, greater -0.40 and the greatest -0.26...

This was fun if you have anymore of these feel free to message me on here if you need help
The two equations graphs intersect and the points where they are touching are belonging to both graphs therefore solutions for both equations.
(2) points (x,y) are
(-1,0) (-1)^2. +0^2=1; 1=1 ✔️
0=-1+1; 0=0✔️
(0, 1). (0)^2. +1^2=1; 1=1 ✔️
1=0+1; 1=1 ✔️
