Answer:
90⁰
Step-by-step explanation:
y=cosx
y'= -sinx
eqñ of tangent is y=-x
slope of tangent =-1
we know...
slope of tangent = y' or derivative of y
-sin x = -1
sin x= 1
x = 90⁰
Answer:
FE
Step-by-step explanation:
The radius of a circle is the line segment from the centre of the circle to a point on the circle.
F is the centre of the circle, thus
FA, FE, FD, FC and FB are all radii of the circle
Answer:
3, 5, 7
Step-by-step explanation:
As per triangle inequality theorem:
- <em>Any side of a triangle must be shorter than the other two sides added together</em>
Assume the sides are equal to 3 smallest odd numbers: 1,3 and 5
- Then 1+3< 5 and it is against the above rule, so this is not correct
The next triple is: 3, 5 and 7
- Then 3+ 5 > 7 and it is correct
So 3, 5, 7 is the combination of smallest odd numbers to make sides of a triangle

A combination is the weight of the two dogs added. If one dog weighs 15 kilos, while the other weighs 13 kilos, we must add 15 to 13. 15 plus 13 is 28, so the combination of the two dogs is 28.
