Example 1: Find the unknown 'y in the following figure;
Wel
Solution
Nov
We know that
y + 125 = 180
Linear pair
y = 180 - 125
B
C
D
y = 55
Example 2 Find the unknown angles in the following figure:
Solution
We know that
y + 120 = 180
Linear pair
y = 180 - 120
V
120
y = 60
С
D
Now, x + 60+ y = 180
(Sum of angles of a A)
x + 60 + 60 = 180
x + 120 = 180
x = 180 - 120 = 60
Example 3: Find the unknown angles in the following figure,
Solution:
We know that:
(Sum of angles of a A)
50
50 +60 + y = 180
y + 110 = 180
y = 180 - 110
XN
60°
y = 70

Answer 1

Answer:

(22+23)= 24

when you add 22+23+125= 170

y= 180-170

y= 10

when you do 24*20/20 = 24
