If the measure of angle 4 is 70 degrees, what is the measure of angle 1?

If The Measure Of Angle 4 Is 70 Degrees What Is The Measure Of Angle 1 class=

Sagot :

Answer:

angle 1= 110 degrees

Step-by-step explanation:

A line = 180 degrees

Since angle 1 and 4 make a line then both of them have to equal 180 degrees.

So, you would just subtract 180-70(angle 4)= 110 which gives you angle 1.

You could do the same with angle 4 and 3, angle 3 and 2, and angle 2 and 1 since they all form a line.
