AP State Syllabus 7th Class Maths Solutions 4th Lesson Lines and Angles Exercise 2<\/h2>\n

\"AP<\/p>\n

Question 1.
\nWhich of the following pairs of angles are complementary?
\n\"AP
\nSolution:
\nIn fig (i) 110\u00b0 – 30\u00b0 = 140\u00b0 \u2260 90. Hence they are not complementary.
\nIn fig (ii) 90\u00b0 + 90\u00b0 = 180 \u2260 90\u00b0. Hence they are not complementary.
\nIn fig (iii) 80\u00b0 + 10\u00b0 = 90\u00b0 = 90. Hence they are complementary.<\/p>\n

Question 2.
\nFind the complements of the given angles. Find the complementary angles of the following.
\n(i) 25\u00b0
\n(ii) 40\u00b0
\n(iii) 89\u00b0
\n(iv) 55\u00b0
\nSolution:
\ni) Complementary angle of 25\u00b0 = 90\u00b0 – 25\u00b0 = 65\u00b0
\nii) Complementary angle of 40\u00b0 = 90\u00b0 – 40\u00b0 = 50\u00b0
\nill) Complementary angle of 89\u00b0 = 90\u00b0 – 89\u00b0 = 1\u00b0
\niv) Complementary angle of 55\u00b0 = 90\u00b0 – 55 = 35\u00b0<\/p>\n

\"AP<\/p>\n

Question 3.
\nTwo angles are complement to each other and are also equal. Find them.
\nSolution:
\nLet the angle be x\u00b0
\nThen Its complement = (900_ x\u00b0)
\nBy problem, x\u00b0 = 90\u00b0 – x\u00b0
\nx\u00b0 + x\u00b0= 90\u00b0
\n2x = 90\u00b0
\nx = \\(\\frac{90^{\\circ}}{2}\\)
\nx = 45\u00b0<\/p>\n

Question 4.
\nManasa says, \u201cEach angle in any pair of complementary angles is always acute\u201d. Do
\nSolution:
\nYes. Each angle \u00a1n any pair of complementary angles is always acute.
\nAs sum of two angles is 90\u00b0, each of the angle must be less than 90\u00b0.<\/p>\n","protected":false},"excerpt":{"rendered":"
