Answer:
d
Step-by-step explanation:
csc²θ-cot²θ=1
csc²θ-(4/3)²=1
csc²θ=1+16/9=25/9
cscθ=√(25/9)=5/3
Answer:
x / -9 = -16
Step-by-step explanation:
Answer:
50%
Step-by-step explanation:
one fourth of 100 is 25 and 25 times two is 50, 50/100 = 2/4 = 50%
Answer:
The correct option is (a).
Step-by-step explanation:
The vertices are equidistant from the circumcenter.
Circumcenter of a triangle is a point where the perpendicular bisectors are intersection each other.
In figure (a) the point P is the intersection point of all perpendicular bisector, therefore point P is the circumcenter of triangle ABC and the point P is equidistant from A,B and C.
Therefore option (a) is correct.
In figure (b) the point P is the intersection point of all perpendicular, therefore point P is not the circumcenter of triangle ABC.
Therefore option (b) is incorrect.
In figure (c) the point P is the intersection point of all bisectors, therefore point P is not the circumcenter of triangle ABC.
Therefore option (c) is incorrect.
In figure (d) the point P is the intersection point of all medians, therefore point P is not the circumcenter of triangle ABC.
Therefore option (d) is incorrect.
