$x=amount\ of\ each\ coin. \\ .25x+.1x=1.4 \\ .35x=1.4 \\ x= \frac{1.4}{.35} \\ x=4\ of\ each\ coin. \\ 4\ quarters\ and\ 4\ dimes. \\ \boxed{8\ coins\ in\ total}$

Answer : 110 degree

To find angle 1 , we apply outside angle theorem Lets name each point Measurement of arc EF=280 degrees

Measurement of arc GH = 60

Angle D = angle 1

Please refer to the theorem attached below

$angle D = \frac{arc(EF)-arc(GH)}{2}$

Now we plug in the values

$angle 1 = \frac{280-60}{2}$

angle 1 = 110

Measurement of angle 1 = 110 degrees
