Estimate the sum of 604 and 235 by rounding both values to the nearest hundred. what is the best estimate of the sum? plz me plz

Hello!

604 rounded to the nearest hundred is 600, while 235 rounded to the nearest hundred is 200. 

Now, add the rounded values.

600 + 200 = 800

The estimated sum of 604 and 235 is 800. 

:)

Well you would round 604 to 600 and 235 to 200 so the answer is 800

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
