Answer:

b = 55 degrees

Step-by-step explanation:

The angles 30, a, b and 45 must sum up to 180 degrees

Subtracting (30 + 45) from both sides leaves us with a + b = 105 degrees.

But b = a + 5.  Substituting a + 5 in the equation above yields

a + a + 5 = 105 degrees, so that

2a = 100 degrees, and a = 50 degrees.  Then b = a + 5, or b = 55 degrees.

Darina [25.2K]

Answer:

im assuming its daily

Step-by-step explanation:

If you have a credit card with a 24% APR, that's the rate you're charged over 12 months, which comes out to 2% per month. Since months vary in length, credit cards break down APR even further into a daily periodic rate (DPR). It's the APR divided by 365, which would be 0.065% per day for a card with 24% APR. Hope this helps. :D
