We need to compute the slope of the graph shown

m = (y2 - y1)/(x2 - x1)
m = (25-10)/(5-2)
m = 15/3
m = 5

The slope of 5 means the graph tells us "she is walking 5 feet per second".

So the first part of her walk is at 4 feet per second, then the second part of her walk is at 5 feet per second. The second part of her walk is faster. As a story scenario, perhaps she realizes she is going to be late getting home which is why she is walking a bit faster now.

Find the measure of the largest angle in ABC if a = 12, b = 8 and c = 13.
Papessa [141]

Answer:

C=78.28^{\circ \:}

Step-by-step explanation:

We are given a triangle

whose sides are

a=12

b=8

c=13

Since, c is largest among them

So, angle C must be largest angle

we can find angle C

we can use law of cosine formula

cos(C)=\frac{a^2+b^2-c^2}{2ab}

now, we can plug values

cos(C)=\frac{12^2+8^2-13^2}{2\times 12\times 8}

cos(C)=\frac{13}{64}

now, we can find angle

we get

C=78.28^{\circ \:}
