Question

What is the measure of ADC

Answer 1

Step-by-step explanation:

By Angle Sum property,

(3x+6)+ (7x-4)+90=180

10x+92=180

x=88/10

x=8.8

Now Z ADC= (3x+6)°

=(3×8.8)+6

=26.4+6

=32.4°

Have a Great time

Answer 2

Step-by-step explanation:

The total angle of a right angled triangle is 180°

So,

(7x+4) + (3x+6) + 90° = 180°

7x+4+3x+6+90=180

10x+100 =180

10x = 180 -100

10x = 80

x = 80/10

x = 8

In the figure given that ADC = 3x + 6

=3(8) + 6

=24+6

=30°

I hope this answer will helps you.
