Answer:
A. 71
Step-by-step explanation:
70+39= 101
101+71=180
Round the first number to its nearest tens, and the second number to its nearest ones. After that, multiply 100 by 4 and you'll get 400.
102.2 x 4.3 = 439.46 is the actual, calculated answer because you asked "can someone please solve" at the end of the question.
-|-32| the answer is -32 so the opposite is 32
Answer: 224
Step-by-step explanation:
The total degrees of a 7-sided shape is 900. You can find that out using the equation (n-2) times 180. Where n is the number of sides. If you add up all the interior angles they equal 676. Then just subtract 676 from 900. 900-676= 224 degrees. That is the missing interior angle.
