Question

2. Find the angle measure x in the following
figure.
ว
a)
125
125​

Answer 1

Answer:

x+125=125

x=125-125

x=0

Answer 2

Step-by-step explanation:

outer angle : 1 ) 125

so 180 - 125 =55 inner angle

2) same as 1st angle

3 ) 55 + 55+ ( 180 - X ) =180

so , X =110

( or )

sum of outer angle of triangle is 360 degree

so , 125 + 125+ X =360

250 + X = 360

X = 110°
