Answer:
x=13
Step-by-step explanation:
3x+78 +x+50=180
3x+x+78+50=180
4x+128=180
4x=180-128
4x=52
4x/4=52/4
x=13
using the principal of straight line angle
Answer: A: V is an acute angle, so it is less than 90 degrees. I would say it's around 45 degrees.
B: K is also an acute angle, but it is fairly close to being 90 degrees, so I'd say around 80 degrees.
C: Q is an obtuse angle, so it is over 90 degrees but less than 180 degrees. I would say it's around 110 degrees.
D: Y is an obtuse angle. It is very close to 180 degrees. I would say it's around 160 degrees.
Step-by-step explanation:
To solve the speed you need to do distance divided by time. So 24 divided by 60 is 0.4m/s (this might be wrong)
