Answer:
The two other angles are 29 degrees and 61 degrees
Step-by-step explanation:
There are 180 degrees in a triangle. Given this is a right triangle one of the angles is 90 degrees. As in the other two angles have to equal up to 90 degrees. Now we have to find x.
180 - 90 = 90
If x equals 28
28 + 1 = 29
2 x 28 + 5 = 61
29 + 61 = 90
The two other angles are 29 degrees and 61 degrees
It means 8x is smaller or equal to 48
Okay all you have to do is complete the square of the x and y's
so divide the coefficient of x by -2, then square it all and minus the square of the coefficient of x
hence (x-3)^2 - 9
then do the same for y
(y-4)^2 - 16
so (x+3)^2 + (y+4)^2 = 36
the radius is the root of the 36 so 6, and the centre is (-3,-4) because it's whatever would make the (x+3) or (y+4) equal to 0
Answer:
x=-2
Step-by-step explanation:
-2x-4=8+4x
-6x=8+4
-6x=12
divide both side by -6
x=-2
