Question

Угол А=40 угол B=140 найди угол С, если угол Д 70

Answer 1

в четырех угольнике всего 360 градусов....

чтобы найти угол С надо все сложить и отнять от 360 градусов.

360-(140+40+70)=110°

Answer 2

To find the measure of angle C, we can use the fact that the sum of angles in a quadrilateral is equal to 360 degrees.

In this case, we have the following information:

Angle A = 40 degrees Angle B = 140 degrees Angle D = 70 degrees

Let's calculate the measure of angle C:

Step 1: Add up the given angles to find the sum of angles in the quadrilateral:

Sum of angles in the quadrilateral = Angle A + Angle B + Angle C + Angle D

Step 2: Substitute the given values into the equation:

360 degrees = 40 degrees + 140 degrees + Angle C + 70 degrees

Step 3: Solve for Angle C:

Angle C = 360 degrees - (40 degrees + 140 degrees + 70 degrees) Angle C = 360 degrees - 250 degrees Angle C = 110 degrees

So, the measure of angle C is 110 degrees.
