Us of pond 15A. एउटा वृत्ताकार पोखरीको परिधि 176 मि. छ र यसको वीचमा एउटा खम्बा गाडिएको छ । एउटा व्यक्तिले पोखरीको किनाराको कुनै ।
पनि ठाउँबाट खम्बाको टुप्पोको उन्नतांश कोण 60° पाएछ भने सो खम्बाको पानीमाथिको उचाइ पत्ता लगाउनुहोस् ।
The circumference of a circular pond is 176 m and a pillar is fixed at the centre of the pond. If a person
finds the angle of elevation of 60° of the top of the pillar from any point on the bank of the pond, find the
height of the pillar above the water level.

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
