Which type of triangle contains its centroid?

a. right
b. acute
c. obtuse
d. all of the above

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

y + 11 = (1/4)(x + 16)

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
