I’m not sure but i really really really like points!!!!
So, first turn your fractions into decimals. ⅞ = 0.875 which rounded is 0.88. 4/5 = 0.8. Next, put the decimals into the equation to replace the fractions. 0.88 + 4.2 - 0.8. Next solve the problem. So 0.88 + 4.2 = 5.08. Now your equation should look like this 5.08 - 0.8. Then subtract 0.8 from 5.08 which gives you 4.28. So 4.28 is your answer.
Answer:
reflection
Step-by-step explanation:
it goes against the y axis
Assuming you have some angle measures, you could use the
Law of Sines to solve for the missing side lengths, which states that,

,
where a, b, and c correspond to the given sides you have, and A, B, and C represent the angles you have.
In this scenario, you would have to have the values for c (which we do), and have the angle measure of C. In addition, we would also need an angle measure that is either A or B.
Hope this helps a bit!
