Hi there!
In order to solve, we can first set the values of angle E and angle N equal to each other.
WORK:
Now that we have the value of x, we can plug it in for the angles we need to find.
WORK:
Angle E = 5^2
Angle E = 25
Angle N = 4(5^2) - 75
Angle N = 100 - 75
Angle N = 25
ANSWER:
A - Angle N and Angle E both equal 25
Hope this helps!! :)

Answer:
9/8 first 11/8 second and third is 75
Step-by-step explanation:
Answer:
1/8
Step-by-step explanation:
Kylie's little brother ate 1/4 of 1/2 of the cake. This means he ate 1/8 of the whole cake, since 1/2 is 0.5 of the whole cake, and that means that to find the fraction of what her brother ate, you must divide 1/4 in half, which is 1/8.
The number of weeks it will take both Sam and Marshall to have the same amount of savings in their accounts is 48 weeks
Given:
<em>Amount with Sam </em>= $2,500
<em>Additional savings each week</em> = $40
<em>Amount with Marshal</em> = $7,300
<em>Amount spent each week</em> = $60
let
x = <em>number of weeks</em>
<em>Sam equation:</em>
2500 + 40x
<em>Marshall's equation:</em>
7300 - 60x
Equate both
2500 + 40x = 7300 - 60x
<em>collect like terms</em>
2500 - 7300 = - 60x - 40x
-4800 = -100x
divide both sides by - 100
x = -4800 / -100
x = 48 weeks
Therefore, the number of weeks it will take both Sam and Marshall to have the same amount of savings in their accounts is 48 weeks
