45°?
Step-by-step explanation:
The second floor of a building is 20 m above the ground.
From this floor, the angle of
elevation of the top of an eucalyptus tree is 15°
and the angle of depression of the foot of the same tree is 10°
10+15+20=45
A8% is X
10% is 700-X
X(.08)+ .10(700-X)= 64
.08x+ 70-.10X=64
-.02X+70=64
-70=-70
-.02x= -6
Divide by -.02
X= 300
Answer $300 was invested at 8%
Check 300 times .08= 24. 700-300=400 times .10 = 40 and 24+40=64
