110 · واحدهای پذیرفته‌شده: degrees · degrees Celsius

توضیح

Neighbouring angles of a parallelogram sit between the same pair of parallel sides and therefore complete 180 degrees together, so each one beside the stated angle is 180 minus 70. Entering 70 answers for the angle across the shape, which is the one that repeats, not the one alongside.
