Two points a and b are on opposite sides of a building. a surveyor selects a third point c to place transit. point c is 62 feet
lorasvet [3.4K]
Okay, so basically you are going to use the Pythagorean Theorem which states: If a right triangle has sides a and b and hypotenuse c then a2+b2=c2.
You already have the distance between AC and BC so you want to figure out the distance between AB. All you have to do is plug in the information. If you draw out a picture, it will help you to visualize it.

Find the sum of 136 +212. expkain why u did r did not regroup
mario62 [17]
Line up 136 and 212 with 136 on top and 212 on the bottom.

  136
+212
____

now add up the end numbers, 6 and 2. That's 8. Since 8 is only a single-digit number, it fits in the space. Write that down under 6 and 2. 
Next, add up the middle numbers, 3 and 1. That's 4, it fits in the space, so you don't need to regroup here either. 
Now add up the first number in each, and that adds up to 3. 

The sum is the number you wrote down! It should look something like this.

  136
+212
____
348

You can say that the sum of these numbers is 348, and you did not have to regroup because the sums of each digit was under 10!
