Question

find the value of x in the following figures ​

Answer 1

Step-by-step explanation:

all are exterior Angeles

so sum of two interior opposite angles equal to exterior angle

$1. \: x = 60 + 70 \\ x= 130$

2.

$x = 40 + 60 \\ x = 100$

3.

$x = 75 + 65 \\ = x = 130$

Answer 2

Answer:

130°

Step-by-step explanation:

First find the angle of the inner one

Let it be y

So it will be

180=70+60+y

180=130+y

180-130=y

y=50

Now we have to subtract it by 180

x=180-y

x=180-50

X=130
