Answer:
The first set of expenses is 75% of the second assuming we are in a 30-day month.
Step-by-step explanation:
To find this, we first have to find out how much we spend a month in coffee. To do so, we multiply the daily cost by number of days in a month (we'll use 30 for this case).
$3 * 30 days = $90 a month.
Now to find the percentage, we divide what we spend in coffee by what we spend on gas.
$90/$120 = 75%

Answer:</h2><h2>x=37.5° and angle ABC is 52.5°</h2><h2>
Step-by-step explanation:</h2>
We know that angle CBD is a right angle.
We also know that angle ABE is 180°.
Our unknown angle values are angle DBE and angle CBA.
angle CBD minus angle ABE will be 90°.
angle ABC plus angle DBE must equal 90°.
Solving for x:
(x+15)+(x)=90°
(x+15-15)+(x)=90°-15
(x)+(x)=75°
2x=75°
2x/2=75°/2
x=37.5°
Checking the work:
ABC=37.5°+15=52.5°
CBD=90°
DBE=37.5°
In conclusion, ABC plus CBD plus DBE equals 180°
