(x-4)^2-19=y
you first add the three to the other side, then add 16 on both sides, make the left side x-4 squared, and lastly you subtract 19 from both sides.
Answer:
8. Obtuse
11. Obtuse
Step-by-step explanation:
c^2 = a^2 + b^2
for 8, it's 6 squared plus 9 squared, which is 117. now, 15 squared is 225. 225 is bigger than 117, which makes it obtuse. if the two results equaled each other, it would be a right triangle. if the 2 smaller numbers when squared were bigger than the hypotenuse squared, then it would be acute
C! All angles are the same
Dude stop commenting that people need real answer not a link
Answer :- Just try area/2 or half the area of the triangle
