State if the triangle is right

The Triangle is a right angle

Step-by-step explanation:

I can tell because if I hold up the edge of a paper to the corner between the lengths 28.5 cm and 38 cm the paper fits. Therefor, the triangle is in fact a right triangle.

the triangle is not a right angle. it is obtuse and acute

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
