Answer: C
Step-by-step explanation:
We know that A and D will not be the correct answers. For A, it's only one 90 angles, but the questions said that has two angles. For D, it's two angles : 90 and 12, but in the question, 12 is the length, not the angle.
The correct answer is C.
Answer:
0
Step-by-step explanation:
You first multiply -2(-2) which will be 4 since a negative times a negative is a positive. Next you subtract 4 and -4 which is 0. Lastly you bring down the y which is equal to 0.
This triangle is a scalene triangle because all three of the side lengths aren't equal.All of the three angles have different measures.This triangle would have been classified as acute because the angles are less than 90 degrees.If all angles were 90 degrees then it would be right and if they were more than 90 it would have been an obtuse triangle.Hope this helped!!!!!!!!
check the picture below, you can pretty much count the units off the grid.
recall that A = (1/2)bh.
