Can someone please help me with 1,2 please

1) This HAS a right angle

2) This is an obtuse triangle

Step-by-step explanation:

1)

4² + 3² = 5²

16 + 9 = 25

25 = 25 ✅

2)

5² + 6² = 8²

25 + 36 = 64

61 ≠ 64 ❌

Since c is bigger, this is an obtuse triangle

.

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
