Sagot :

Answer:

145

Step-by-step explanation:

Angle 4 would be equivalent to 1, which means that 1 and 4 would equal 70.

In a circle the angles must equal 360.

So you would do 360 - 70 which equals 290.

The same rule for angles 1 and 4, applies to 2 and 3.

So you would half 290.

Thus, the answer would be 145 degrees.

Hope this helps :)
