Equation: 180° - 75°
Measure: 105°
A straight line has an angle measurement of 180°. Since we have GFB, 75°, we can find EFB this way.

Equation: 90° - 40°
Measure: 50°
The little box in the angle shows that it is equal to 90°. Since they give us HGB, 40°, we can solve for EFB using this information.
The answer is 8/25
Hope it helped
It would be 20 years because if En is 100 Mark will be 25. 25 times 4 is equal to 100
T=4(r-1.5)
4(3.59-1.5)=t= 8.36 dolla
Enjoy.
Since it is 4 times as many quarters and dimes, you can use a chart for guess and check. I started with 8 dimes and 32 quarters.
If you keep going, you end up with the fact that there are 36 quarters and 9 dimes.
