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.

2x + 1 < 5 solve the following inequality. then place the correct number in the box provided.

Atechnician compares repair costs for two types of microwave ovens (type i and type ii). he believes that the repair cost for type i ovens is greater than the repair cost for type ii ovens. a sample of 6767 type i ovens has a mean repair cost of $79.79$⁢79.79. the population standard deviation for the repair of type i ovens is known to be $19.18$⁢19.18. a sample of 5555 type ii ovens has a mean repair cost of $75.24$⁢75.24. the population standard deviation for the repair of type ii ovens is known to be $21.40$⁢21.40. conduct a hypothesis test of the technician's claim at the 0.050.05 level of significance. let μ1μ1 be the true mean repair cost for type i ovens and μ2μ2 be the true mean repair cost for type ii ovens. step 2 of 4 : compute the value of the test statistic. round your answer to two decimal places.
