Answer:
95°
Step-by-step explanation:
Angle 1 and 4 are opposite angles, thus equal, so:
3x+10 = 4x-15 =>
x = 25
Angle 1 and 4 are 85°
Angle 4 and angle 6 are called allied (or co-interior) angles, which are supplementary, i.e., angle 6 = 180 - angle 4, so angle 6 = 95°.
Angle 6 and 7 are again opposite, so angle 7 is 95° as well!
Answer:
the answer i think is $259200
Step-by-step explanation:
if the bank charges 7.2% every year, and in this case it's 4 years, then that would mean it would be 28.8%(7.2 x 4), which means the answer would be 9000 x 28.8 which is 259200.
