Express the first quantity as a fraction of the second 650m,1.95km

The first quantity represent 1/3 of the second quantity

Step-by-step explanation:

Remember that

To convert kilometers to meters, multiply by 1,000

we have

650 m

1.95 km ----> convert to meters

we know that

To express the first quantity (650 m) as a fraction of the second quantity (1,950 m), divide the first quantity by the second quantity

so

Simplify

Divide by 650 both numerator and denominator

therefore

The first quantity represent 1/3 of the second quantity

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 .
