Question

Angles x and y are adjacent angles State whether their exterior arms are in a straight line where 1) x=55 and y=115 2) x=3/5right angle and y=126

Answer 1

Complementary angle = 900 - given angle

(i) Complement of 200 = 900 – 200 = 700

(ii) Complement of 630 = 900 – 630 = 270

(iii) Complement of 570 = 900 – 570 = 330

Answer 2

Answer:

1) X = 55 , y= 115

X+y = 170

exterior arm is not in a straight line

2) X= 3/5 right angle = 54

y= 126

X+y= 180

exterior arm is in a straight line
