Answer:
1. the interior angle measure of a parallelogram is 360 degrees
2. diagonal of a parallelogram bisect it into two congruent triangles
3. opposite angles of a parallelograms are congruent
4. a parallelogram has two pairs of parallel sides.
5. consecutive angles of a parallelogram are supplementary
Step-by-step explanation:
Alternate exterior angles(AEA).
Given their relationship the angles are congruent.
8x-71=5x+7
3x-71=7
3x=78
X=26
If it's a perfect square, then it's easy. However, if it's not a perfect square, use the square root button on your calculator. IF you happen to know calculus then you could use Newton's Method....but I'm thinking you're not there yet. So stick with the calculator.
