Answer: The value of x =2 units.

Explanation:

Since we have given that

AD= CD

BE= EA

So, we get that D and E are the mid-points of AC and AB respectively.

So, by Mid- point theorem , which states that the line joining the two midpoints is parallel to third side and it is half in length of third side i.e.

DE=\frac{1}{2}BC

So, we put the value of DE  and BC ,

5x-3=\frac{1}{2}\times (x+12)\\\\2(5x-3)=x+12\\\\10x-6=x+12\\\\10x-x=12+6\\\\9x=18\\\\x=\frac{18}{9}=2

Hence, the value of x =2 units.

I’ve been stuck on this for awhile please I need help

Answer:

y = 96°

Step-by-step explanation:

The measure of the inscribed angle y is half the measure of its intercepted arc.

The whole circle = 360°

the intercepted arc = 360° - 168° = 192°

Thus

y = \frac{1}{2} × 192° = 96°
