Question

x मीटर ऊची एक मूर्ति भूमि से 100 मीटर ऊचे चबूतरे पर खड़ी है। भूमि पर स्थित एक बिटु से मूर्ति के शीर्ष बिटु का उन्नयन कोण 60° है और चबूतरे के शीर्ष बिंदु का उन्नयन कोण 45 है। मूर्ति की ऊचाई ज्ञात कीजिए।​ ​​

Answer 1

Answer:

In contrast to President Hoover, who believed that the Depression arose from international circumstances, Roosevelt believed that the nation's economic woes were largely home-grown. As a result, FDR rejected Hoover's numerous entreaties (delivered during the period between FDR's election and inauguration) that the incoming administration support Hoover's approach to the upcoming London Economic Conference. Hoover hoped that in London the United States and other leading industrial nations would devise a currency stabilization program and pledge its support for the international gold standard.

Answer 2

Answer:

x= (√3 - 1)100 m

Step-by-step explanation:

मूर्ति की उचाई (AD) = x

चबूतरे की उचाई (AC) = 100 m

चबूतरे के शीर्ष बिंदु का उन्नयन कोण = 45°

∆ABC में,

tan45° = BC/AB

=>. 1 = 100/AB

=>. AB = 100 m

∆ ABD में,

tan60° = BD/AB

=>. √3 = BD/100

=>. BD= 100√3

अतः मूर्ति की ऊँचाई = x = BD - BC

x = 100√3 - 100

=> x= (√3 - 1)100 m
