Answer:
105° is the measurement of the original angle.
Step-by-step explanation:
Let the measure of an angle is x.
Then by the statement of the question we can form an equation
x - 15 = 90
(When 15 is subtracted form the measure of an angle, the result is the measure of a right angle)
x = 90 + 15 = 105°
Therefore the original angle is 105°.

Answer:
$100 can be saved.
Step-by-step explanation:
A couch sells for = $1260
The same couch can be brought by paying 400 down payment and $80 per month for 12 months.
Total amount will be paid = 400 + (80× 12)
= 400 + 960
= $1,360
Difference between the amounts = 1360 - 1260
= $100
You can save $100 by paying the total amount at the time of the purchase.
