If the angles of a triangle are in the ratio of 1:2:3 , find the value of all the angles of the triangle. Let the angles of the triangle be 1x°, 2x° and 3x°. We know that sum of all angles of a triangle is 180°. So, 1x° + 2x° + 3x° = 180°. 6x° = 180°. x° = 180°/6 = 30°. Hence, Angles of the triangle (i) 1x° = 1 × 30° = 30° (ii) 2x° = 2 × 30° = 60° (iii) 3x° = 3 × 30° = 90°.

Essay type question:- 1. Peninsular river system

Posted by Niharika Rawat 3 years, 5 months ago

Jose P Vincy 3 years, 5 months ago

The Peninsular Rivers The main water divide in Peninsular India is formed by the Western Ghats. Most of the major rivers of the Peninsula, such as the Mahanadi, the Godavari, the Krishna and the Kaveri flow eastwards and drain into the Bay of Bengal. These rivers make deltas at their mouths. The Narmada and the Tapi are the only long rivers, which flow west and make estuaries. 1) The Narmada Basin The Narmada rises in the Amarkantak hills in Madhya Pradesh. The Narmada flows through a deep gorge at the ‘Marble rocks’ near Jabalpur. At Dhuadhar falls the river jumps over steep rocks. The Narmada basin covers parts of Madhya Pradesh and Gujarat. 2) The Tapi Basin The Tapi rises in the Satpura ranges, in the Betul district of Madhya Pradesh. Its basin covers parts of Madhya Pradesh, Gujarat and Maharashtra. 3) The Godavari Basin The Godavari is the largest Peninsular river. Its length is about 1500 km. It rises from the slopes of the Western Ghats in the Nasik district of Maharashtra. The basin covers parts of Maharashtra, Madhya Pradesh, Odisha and Andhra Pradesh. The Godavari is joined by a number of tributaries, such as the Purna, the Wardha, the Pranhita, the Manjra, the Wainganga and the Penganga. Owing to its length and the area it covers, it is also known as the Dakshin Ganga. 4) The Mahanadi Basin The Mahanadi rises in the highlands of Chhattisgarh. The length of the river is about 860 km. Its drainage basin is shared by Maharashtra, Chhattisgarh, Jharkhand, and Odisha. 5) The Krishna Basin It rises from a spring near Mahabaleshwar. The length of the river is about 1400 km. Its drainage basin is shared by Maharashtra, Karnataka and Andhra Pradesh. 6) The Kaveri Basin The Kaveri rises in the Brahmagri range of the Western Ghats. The total length of the river is about 760 km. Its basin drains parts of Karnataka, Kerala and Tamil Nadu. The BaitaThe Subarnrekha
