Answer:
First we have to calculate z
z + 69° = 180°
z = 180° - 69° = 111°
Now that we have 2 out of 3 angle already, we can easily calculate x which is the measurement of the third angle we are looking for:
23° + 111° + x = 180°
x = 180° - 23° - 111°
x = 46°
Answer:
x = 9 (it is seriously not drawn to scale)
Step-by-step explanation:
BC = DC^2 + BD^2 (Pythagorean theorem)
BC = 4^2 + 6^2
BC = 16 + 36
BC = 52^2
BC = 2sqrt13
BC/AB = DC/BD
(2sqrt13)/AB = 4/6
6(2sqrt13) = 4(AB)
12sqrt13 = 4AB
3sqrt13 = AB
AC^2 = AB^2 + BC^2 (Pythagorean Theorem)
AC^2 = (3sqrt13)^2 + (2sqrt13)^2
AC^2 = 117 + 52
AC^2 = 169
AC = 13
AD + DC = AC
AD + 4= 13
AD = 9
Answer:
y+3=-3(x+1)
Step-by-step explanation:
y-y1=m(x-x1)
m=-3
y-(-3)=-3(x-(-1))
y+3=-3(x+1)
Assuming that it is a square board, she would not have enough. This is because there would be twice as much height and twice as much width. Those numbers add up to far more.
However, if they just have to cover those two sides they will have 0.45 left. You can get this by subtracting the amounts from the overall.
46.25 - 37.5 - 8.3 = 0.45
