Answer:
height for the building = 551.8 ft
Step-by-step explanation:
The info given describes the shape of a right triangle.
Thus:
Reference angle = Angle of elevation = 23°
Opposite side = height of the building = ?
Adjacent side = 1,300 ft
Apply trigonometric function, TOA:
Tan 23 = Opp/Adj
Tan 23 = Opp/1,300
1,300 × Tan 23 = Opp
551.817261 = Opp
Opp ≈ 551.8 ft
height for the building = 551.8 ft

Answer:
Step-by-step explanation:
So we know they had got $22,553 which is 90% more than last year. With this information we know:
190% = $22,553
1% = $22,553/190
1% = $118.70
100% = $11870
So overall it would be $11870 which they had got last year
