Step-by-step explanation:</h3>
The point of intersection of the perpendicular bisectors of a triangle is the circumcenter, the center of the circle that contains the three triangle vertices.
If that center is on one side, that side must be a diameter of the circle. The diameter cuts the circle into two arcs, each of which measures 180°.
The third vertex of the triangle and its two legs form an inscribed angle that subtends an arc of 180°. The measure of that angle is half the measure of the arc, so the angle measures 90° and is a <em>right angle</em>.
A triangle with a right angle is a right triangle. QED
Answer:
-3.8
Step-by-step explanation:
1.6(2.5-10) + 8.2
1.6(-7.5) + 8.2
-12 + 8.2
-3.8
Answer:
3y
Step-by-step explanation:
The missing term is 3y since the following like terms combine:
These terms are the same as the sum listed except -18y.
What must be added to -18y +____=-15y.
-18y+_3y__ =-15y
3y is the solution.
