When the length of sides are given, you can use law of cosine to find the angles
Refer to this website for details
https://www.mathsisfun.com/algebra/trig-cosine-law.html

11^=8^2+5^2-2*8*5cosA
-80cosA=32
cosA=-0.4
A is about 114 degree
use the same method to find out B and C, you will get 42 and 25

write a word problem in which you multiply a fraction by a number greater than 1. Estimate the product then compare the product
tangare [24]
Answer:

Word problem: A recipe for making cookies use half cup of sugar for 1 cup of flour to make one pound of cookies. How many cups of sugar you need to make 3 pound of cookies.

As you can see to solve that problem you need to multiply the fraction 1/2, which is the number of cups needed to make 1 pound of cookies, times the number of pounds that you want to make.

So, for this problem you have to multiply 1/2 times 3.

My estimate is that the result is 1.5.

You can verify my estimate by multiplying:


        1        3x1       3
3 x ----- =  ------ = ------ = 1.5
        2.       1x2       2

So, I have shown that my estimate was correct.

On the y-axis of the graph go to 4 (0,4)
Then you will do down 1 and then go 5 right and keep repeating down 1 right 5 from the last point u plotted until you can’t plot anymore.
