Answer:
10x - 3y = -109 .
Step-by-step explanation:
x^2 + y^2 = 109
Implicit Differentiation:
2x + 2y.y' = 0
y' = -2x/2y = -x/y
So at the point (-10,3) the gradient of the tangent is -(-10)/3 = 10/3.
Equation of the tangent:
y - y1 = m(x - x1)
y - 3 = 10/3(x + 10)
y - 3 = 10/3 x + 100/3
3y - 9 = 10x + 100
-109 + 3y = 10x
10x - 3y = -109
Answer:
N + 3 = -5
n= -8
N-4=9
n=13
4+N=10
n=6
-10+N=3
n=13
N-10=1
n=11
-11+n=-12
n=-1
N+19=20
n=1
15+N=-10
n=-25
N-6=-12
n=-6
N+4=16
n=12
Step-by-step explanation:
<span>A right triangle has a 28° angle.
As you know a</span> right triangle<span> is a </span>triangle<span> in which one angle is a </span>right angle that equal 90° angle.
Now you know 2 angles values: 28° and 90°
So the third angle = 90° - 28° = 62°
Answer:
28°, 62°, 90°
