Answer:
#1
<u>Sum of interior angles is 180:</u>
- y = 180 - (42 + 31) = 107
<u>The law of sines:</u>
- x / sin 107 = 11 / sin 42
- x = 11 sin 107deg / sin 42deg
- x = 15.72
#2
<u>The law of cosines:</u>
- cos 76 = (6² + 17² - x² )/2(6)(17)
- 204*0.24 = 325 - x²
- x² = 325 - 48.96
- x² = 276.04
- x = √276.04
- x = 16.61
#3
<u>Same as above:</u>
- 2*9.4*10*cos 20 = (10² + 9.4² - x²)
- 176.66 = 188.36 - x²
- x² = 188.36 - 176.66
- x² = 11.7
- x = √11.7
- x = 3.42
#4
<u>Sum of interior angles is 180:</u>
<u>The law of sines:</u>
- x / sin 34 = 15 / sin 94
- x = 15 sin 34 / sin 94
- x = 8.41
Answer:
x= 3 y=3
Step-by-step explanation:
6(3) - 3(3) =9
18 - 9 = 9
36% in decimal from it .36
172.80 + .36 = 173.16
So original price was 173.16
Answer:
42

Answer:
I would shade 50 squares
Step-by-step explanation:
"Of" is the same as multiplication so,2/4×100/1=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
2×100/4×1=200/4
Since 200 divided by 4 equals 50 then, 200/4=50
Therefore: 2/4 of 100/1=50
