Question

compute the following values of x
a) two vertically opposite angles are 4x° and 52°.
b) a pair of linear angles are 2x and 3x.
c) a pair of complementary angles is (x+5°) and (x+15°)
d) two vertically opposite angles are (3x + 10°) and 73°
e) a pair of linear angle is 5x and (x+120°)


plz answer these questions fast it is urgent

Answer 1

Answer:

a) vertically opposite anglea are equal

=> 4x° = 52° => x = 13°

b) sum of linear angles is 180°

=> 2x + 3x = 180°

=> 5x° = 180°

=> x = 36°

c) sum of two complementary angles = 90°

=> x° + 5° + x° + 15° = 90°

=> 2x° + 20° = 90°

=> 2x° = 70° => x = 35°

d) 3x + 10° = 73°

=> 3x = 63° => x = 21°

e) 5x+ x + 120° = 180°

=> 6x + 120° = 180°

=> 6x = 60° => x = 10°
