Answer:
Step-by-step explanation:
We know that the sum of angles in a quadrilateral is 360 degrees.
So,
angle A + angle B + angle C + angle D = 360 degrees
We are given:
angle A = 3x + 2
angle B = (4x - 24)
angle C = (2x + 2)
angle D = x + 10
Substituting these values in the equation for the sum of angles, we get:
(3x + 2) + (4x - 24) + (2x + 2) + (x + 10) = 360
Simplifying and solving for x, we get:
10x - 10 = 360
10x = 370
x = 37
Now we can find the value of angle D:
angle D = x + 10 = 37 + 10 = 47 degrees
To find angle ADC, we need to subtract angle C from angle D:
angle ADC = angle D - angle C = 47 - (2x + 2) = 47 - (2(37) + 2) = 47 - 76 = -29
The measure of angle ADC is -29 degrees. However, this is not a possible angle measure since angles cannot be negative. This means that there is an error in the problem statement or in the calculations.
