Iam a number rounding to the nearest thousand makes me 1000.all my digits are even their sum is 12 they are in order from greatest to least and no digit is repeated what is the number

The answer is: 642

Step-by-step explanation:

Add 6 + 4 + 2 = 12

You only have 2, 4, 6, 8 to work with. 642 rounded to the nearest thousand is 1,000. The order of 642 is from greatest to least and no number repeats.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
