Answer:
<u>A) 64.7</u>
Step-by-step explanation:
Taking the sine value of the given angle :
- sin 18° = 20/x
- 0.31 = 20/x
- x = 20/0.31
- x = <u>64.7</u> (nearest value)
Margaret has a monthly clothes budget of $50. This implies that she can spend a maximum of $50 on clothes and therefore the maximum value of the domain is 50 to or it can also be said that the domain is all values of domain from 0 to 50.
AREA OF A RECTANGLE IS 42 UNITS
Rectangle: Triangle:
A = L * W A = hb / 2
A = (x-8) * 6 A = (7(x-3)) / 2
A = 6x - 48 A = (7x - 21) / 2
Since the problem states that both rectangle and triangle have the same area.Then:
6x - 48 = (7x - 21) / 2
1) Eliminate the denominator 2 by multiplying both sides by 2.
2 * (6x - 48) = 2 * ((7x - 21) / 2)
12 x - 96 = 7x - 21
Find x. Transfer like numbers and change their signs.
12x - 7x = 96 - 21
5x = 75
5x / 5 = 75 / 5
x = 15
Substitute x by its value:
Rectangle: Triangle
A = (x-8) * 6 - A = (7(x-3)) / 2 Areas of both Rectangle
A = (15 -8 ) * 6 A = (7(15-3)) / 2 and Triangle is the same.
A = 7 * 6 A = (7 * 12) / 2
A = 42 units A = 84 / 2
A = 42 units
Because angleCBD＋angleBDC＋angleC＝180
so angleCBD＋angleBDC＝180－angleC＝180－82＝98
because BC＝DC
so angleCBD＝angleBDC
so 2 angleCDB＝98
so angleCDB＝49
so y＝29

The answer is y = 13/9 or y = 1.444.......
Either answer is correct!
Explanation:
Move the 9 to the other side of the equation, and divide it by 13, which will then get you to a decimal answer of y = 1.444.....
Or, if you don’t want a decimal answer, you don’t have to do the division, you can just leave your answer as y = 13/9
I’m so sorry if the explanation was confusing!
