Answer:
Option B. perpendicular bisector of side AB
Step-by-step explanation:
we know that
The circumcenter is the intersection point of the perpendicular bisectors of a triangle
so
In this problem
The circumcenter O is the intersection point of perpendicular bisector of side AB and perpendicular bisector of side BC
OA=OB=OC ------> the radius of the circle that passes through all three of the triangle's vertices.
therefore
Option B. perpendicular bisector of side AB
Answer:
This is an acute triangle
Step-by-step explanation:
Pythagoras theorem is used to determine if a triangle is right, acute or obtuse
If the sum of squares of two shorter lengths is greater than the square of third side then the triangle is an acute triangle.
If the sum of squares of two shorter lengths is less than the square of third side then the triangle is an obtuse triangle.
If the sum of squares of two shorter lengths is equal the square of third side then the triangle is a right triangle.
so,
As 1600<1945, the given triangle is an acute triangle ..
Answer:
a=175. 93
Step-by-step explanation:
A=2πrh+2πr2=2·π·4·3+2·π·42≈175.92919
Answer:
Step-by-step explanation:
we have
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
remember that
The answer is 1/6 or 2/6. it depends on how many yellow colored beads there are in the box.
