Answer:
(9.37, 17.7) ; (14.10, 19.42); (20.8, 22.3)
Step-by-step explanation:
For the first picture :
The missing angle :
180 - (32 + 90)
180 - (122) = 58°
To obtain the length of side x:
From ptthagoras:
Tan58° = opposite / Adjacent
1.6003345 = 15 / x
x = 15 / 1.6003345
= 9.37
y = sqrt(15^2 + 9.37^2)
y = sqrt(312.7969)
y = 17.7m
2)
Missing angle :
From ptthagoras :
Sin54° = opposite / hypotenus
0.8090169 = y/ 24
y = 0.8090169 * 24
y = 19.42
x = sqrt(24^2 - 19.42^2)
x = sqrt(198.8636)
x = 14.10
3)
Sin21° = opposite / hypotenus
0.3583679 = 8 /y
y = 8 / 0.3583679
y = 22.3
x = sqrt(22.3^2 - 8^2)
x = sqrt(433.29)
x = 20.8
2:1 is the ratio

Answer:

Step-by-step explanation:
The area of a circle is given by 
For circle B, the radius is 3 cm, it has an area of 
Circle D also has a radius of 1 cm. Its area is 
Circle P also has a radius of 1 cm and area 
The area of the shaded region is then 
She earned 661.50 dollars. If she worked 7.5 hrs each day Mon-Wed, she worked 22.5 hrs from Mon-Wed because 7.5 times 3 is 22.5. She also worked 6 hrs on Sat. and 5.25 hrs on Sun., so in total, she worked 33.75 hrs last week. To find out her pay, we have to multiply the total hrs by the amount she gets payed, 19.60. 33.75x19.60 is 661.50, the amount she got payed last week.
