The answer is B. the inequality will always look like that when “at least” is mentioned.
I believe AFE is 0°
CFE is 105°
And BFD is 90° I think
Answer:
The first one is the 3rd option and the second one is the 4th option
Step-by-step explanation:
Answer: As a decimal → 0.8
As a fraction→
or ![\frac{12}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B15%7D)
As a percent→ 80%
Step-by-step explanation:
We can write 12 out of 15 in fraction as ![\frac{12}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B15%7D)
Rewrite it in simplest form by dividing 3 from both numerator and the denominator, we get
![\frac{4}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7D)
To write this in decimal form, just divide the numerator by denominator, we get
![\frac{4}{5}=0.8](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7D%3D0.8)
To write this in percent, multiply the decimal number to 100, we get
![0.8\times100=80\%](https://tex.z-dn.net/?f=0.8%5Ctimes100%3D80%5C%25)
Answer:
Step-by-step explanation:
m∠1+∠2=180
2x+40+2y+40=180
2x+2y=180-80
2x+2y=100
x+y=50
x=50-y
m∠1=m∠3
2x+40=x+2y
2x-x=2y-40
x=2y-40
2y-40=50-y
2y+y=50+40
3y=90
y=30
x=50-y=50-30=20
m∠1=2x+40=2×20+40=80°
m∠2=2y+40=2×30+40=60+40=100°
m∠3=x+2y=20+2×30=80°
