The answer is A. bc of the point
There is a 45,45,90 triangle and a 30,60,90 triangle within triangle ABC.
So you can just use the relationships between sides in these special triangles to find the desired lengths.
AB=3√2
z=3
b=3 (It is isosceles so we know that b=z)
With b=3, we know that...
x=3·2=6
y=3√3
answers: z=3,b=3,x=6,y=3√3
Here, we are required to find how many hours per week does Lindsey need to study if she wants to have an average of at least 90
Lindsey needs to study for at least 15.25 hours to have an average of 90
Given expression:
4(h + 11) – 15
Where,
h = number of hours
For Lindsay to have at least 90
4(h + 11) – 15 = 90
open parenthesis
4h + 44 - 15 = 90
4h + 29 = 90
4h = 90 - 29
4h = 61
Divide both sides by 4
h = 61/4
h = 15.25 hours
Therefore,
Lindsey needs to study for at least 15.25 hours to have an average of 90
