Solution

14) The equation will be

x+130^o+75^o+90^o = 360^o (sum of angles of quadrilateral)

So, x = 65^o

15) Since the sum of the angles is 90^o hence they are complementary.

16) Adjacent AnglesTwo angles are Adjacent if they have a common side and a common vertex and they do not overlap hence 1st angle is 2x and other angle is 3x

2x + 3x = 90 => x = 18^o

17) (B) <NMP & <RMS are vertical angle in this case.

18) Only A,B and D are interior angle of a triangle because their sum is 180

19) A triangle is possible if the sum of two side is greater than 3rd side so A,D and E could form a triangle.

20) If two angle are 60 other two will be sum of 240^o.

22) Clearly 48 feet = 3.2cm

A 1 cm = 48/3.2 feet = 15 feet

B length of the park = 12.8 cm = 192 feet

23) The length of the rom is 64/5 feet = 64/5 x 1/4 = 3.2 inches

24) No triangle could be formed as sum is greater than 180^o

25) 3 feet = 6 inches

1 feet = 2 inches

1 inch = 0.5 feet

parameter is 16 inch or 8 feet.

Area = 60 inch²
