687582 the value of the 8 in the ten thousands place is how many thousands greater than the value of the 8 in the tens place

The easiest way that I've done these is to break it up. The 8 in the ten thousands place is equal to 80,000, and the 8 in the tens place is equal to 80. Then, compare. The ten thousands has 3 more 0s in it then the ten, so therefore it would be 1,000 times greater.

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 .
