5 Beth is designing a business card. She makes a scale drawing of her old business card by using a scale factor of 4
Her scale drawing is a
2.3-inch by 5-inch rectangle
The print shop says that the scale drawing is a reduction of the original card because the original card must be 31
inches by 6 inches. Which explains the print shop's error and gives the correct dimensions of Beth's original card?

In the diagram below what is the approximate length of the minor arc ab

Anyone know? is appreciated! will mark brainliest if correct!

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
