1. By definition, you have:
Sin(α)=Opposite/Hypotenuse
2. Then, SinA is:
SinA=BC/AC
A is the angle in the vertice "A".
BC is the opposite leg to the the angle A.
AC is the hypotenuse of the triangle.
3. By definition, you have:
Cosα=Adjacent/Hypotenuse
4. Then, CosC is:
CosC=BC/AC
C is the angle at the vertice "C".
BC is the adjacent leg to the angle C.
AC is the hypotenuse.
5. Therefore, the answer is the last option:
The equivalent to SinA is CosC
All right triangles will always add up to 90 degrees unless stated otherwise.
Answer:
lets consider two end points are the marked points ,
Then ,
(1,5)=x1,y1
(-1,-3)=x2,y2
line passes through point(1,0)=x3,y3
slope of line ,m = (y2-y1)/(x2-x1)
= (-3-5)/(-1-1)
=4
Eqn of line is:
y-y3=m(x-x3)
y-0 = 4(x-1)
y=4x-4
4x-y=4 is reqyuired eqn..
Step-by-step explanation:
Problem may arise due to calculation but plz check it ...
Answer:
C
because if you arrange orderly ie in an ascending order or a descending order,the middle number is the median and median means average
