Answer:
7.698 m
Step-by-step explanation:
From the question,
Faisal's distance to the flagpole = 30 m
angle of elevation of its top = 12.4°
angle of depression of its bottom = 2.1°
Thus, the height of the flagpole is divided into two parts. Let the upper part be represented by x and the lower part by y.
From the triangle of the upper part (elevation), we have;
tan 12.4° =
x = 30 × tan 12.4°
= 30 × 0.2199
= 6.597 m
From the triangle of the lower part (depression), we have;
tan 2.1° =
y = 30 × tan 2.1°
= 30 × 0.0367
= 1.101 m
The height of the flagpole = x + y
= 6.597 + 1.101
= 7.698 m
The height of the flagpole is 7.698 m.

SOHCATOA or you could have used Pythagorean theorem after you found one of the sides, but I find that it’s quicker to use this.
Answer:
Step-by-step explanation:
We have given:
Principal amount which is 80,000
Time which is 20 year
Rate which is 11.5%
And since, we have to find 13 years early so, time would be: 20-13=7 years.
And since, we have to find for 12 months
Hence, n=12
We have formula to calculate compound interest:
On substituting the values we get:
On simplification we get:
