Answer:
1st - 84. 2nd - Try doing this by yourself first and If you cant get it I'll help you.
Step-by-step explanation:
To find the area of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
An obtuse triangle must have an angle greater than 90degrees (cannot equal 90). Therefore, A. would be the correct answer. This is because A. is the only set of angles that includes an angle greater than 90. Also, all angle measures add up to equal 180degrees.
The answer is 2230. You have to round 27 to the nearest ten and it’s 30 so it’s 2230
