No
if it has 1 acute angle, then the other 2 must be more than 90 each in other words, the other 2 angles must be over 180

all angles add to 180 no more

so no is answer

Urgent ASAP!! Imagine math
Paraphin [41]

Answer:

Graph A = 20miles/gallon

Graph B = 20

Step-by-step explanation:

For graph A, to find the change you will need to choose two points from the graph (the easier the better)

So for example, I've chosen 40miles-2gallons (2, 40) and point 0 (0, 0)

Now you will need to remember the slope formula which is:

m=\frac{y_2-y_1}{x_1-x_2}

so your point (x1, y1) will be (0, 0)

and point (x2, y2) will be (2, 40)

so m=\frac{40-0}{2-0}

which is m=\frac {40}{2} = 20

and so you get that the slope will be 20 miles/gallon

For graph B, what they want you to see is that change of y/change of x means the same as change of miles/change of gallons since x is the gallons and y is the miles.
