Answer:
618 dolla
Step-by-step explanation:
12 hours x the number of hours worked (50) +18
12*50+18
12*50=600
600+18=618
∠CAE = 120°
∠CAD = 60°
∠BAE = 180°
∠DEC = 30°
We start out with the fact that points C and D split the semicircle into 3 sections. This means that ∠BAC, ∠CAD and ∠DAE are all 60° (180/3 = 60).
Since it forms a straight line, ∠BAE is 180°.
Since it is formed by ∠CAD and ∠DAE, ∠CAE = 60+60 = 120°.
We know that an inscribed angle is 1/2 of the corresponding arc; since CD is 1/3 of the circle, it is 1/3(180) = 60; and this means that ∠DEC = 30°.
Answer:
There were 42 fewer students who chose Football than Hockey.
Step-by-step explanation:
Fraction of students who chose Hockey
= 1 - -
=
units = 21
1 unit = 42
No. of students who chose Football
= 2 units ()
= 84 students
No. of students who chose Hockey
= 3 units ()
= 126 students
Difference between no. of students who chose Football and Hockey
= 126 - 84
= 42 students
∴There were 42 fewer students who chose Football than Hockey.
Answer:
area of triangle is 44.45ft^2
Answer:
X = 13
y= 54
Step-by-step explanation:
9x-7=7x+19 (vertical opposite angle)
9x-7x=19+7
2x=26
X=13°
now ,
(9x-7)= 9x13-7=110
(9x-7)+(y+16)=180 sum of the straight angle
110+y+16=180
y=54
