Answer:

C. Circumcenter

D. Orthocenter

Step-by-step explanation:

The centroid is comprised of the medians of the triangle, these are not necessarily perpendicular to the edges of the triangle and therefore it cannot be located with perpendicular segments.

The incenter is made of the angle bisectors of the triangle, which means that they are not being drawn with perpendicular segments.

The circumcenter is found with the perpendicular bisectors of each of the edges of the triangle, therefore it can be located by drawing perpendicular segments.

The orthocenter is comprised of the altitudes of the triangle, these are segments that are perpendicular to each edge of the triangle and run through the vertex that is opposite of that side, therefore it can be located with perpendicular segments.

Solve the right triangle ABC with right angle C if B = 30° and c = 10.
mart [117]

Step-by-step explanation:

Answer:


Last choice is correct.


Step-by-step explanation:


Given that ∠C=90°, ∠B=30°, c=10


We know that sum of all angles in a triangle is 180 degree.


∠A+∠B+∠C=180°


∠A+∠30°+∠90°=180°


∠A+∠120°=180°


∠A=60°


Now we can use sin or cos whichever applicable to find missing sides


2b=10


b=5


Similarly


a=8.6602


Hence last choice is correct.
