Question

Угол 1 =40 градусов 2=140 градусов 3=80 градусов найдите 4

Answer 1

100

40+140+80=260

360-260=100

Answer 2

To find the measure of angle 4, you can use the fact that the sum of angles around a point is equal to 360 degrees. In other words, if you add up all the angles at a point, the total will be 360 degrees.

So, to find angle 4, subtract the sum of angles 1, 2, and 3 from 360 degrees:

Angle 1 + Angle 2 + Angle 3 + Angle 4 = 360 degrees

40 degrees + 140 degrees + 80 degrees + Angle 4 = 360 degrees

220 degrees + Angle 4 = 360 degrees

Now, isolate Angle 4 by subtracting 220 degrees from both sides:

Angle 4 = 360 degrees - 220 degrees

Angle 4 = 140 degrees

Therefore, the measure of angle 4 is 140 degrees.
