Basically estimating is rounding, im going to futher explain this with an example.
For example:
If I wanted to round a number by it's nearest tenth such as 678
(*example)
there are 70 tenths
now when you are estimating when you are rounding to the nearest number if the number has a higher value then 5 you increase the number if it is lower than 5 you STAY the same.
now
678,
since the number next to it is 8, 7 increases and everything else turns into zero. so 678 rounded to the nearest 10th
is 680!
Hope this example helped!
Answer:

Step-by-step explanation:
Since this is a right triangle we can use trig functions
sin theta = opp /hyp
sin 30 = x / 10
10 sin 30 = x
10 * 1/2 = x
5 =x
3/5- -3/4 = 1.35 if you want it as a fraction it’s 27/20
