Question

I’ve tried everything and still can’t get it right help please??

Answer 1

Answer:

Answer D or 23

Step-by-step explanation:

Since the angles are bisected

7x + 30 = 2x + 25

5x = -5

X = -1

Plug in for x

-7 + 30 = 23

Answer 2

Answer:

23°

Step-by-step explanation:

Since ray DC bisects angle BDA, then angles BDC and ADC are congruent. That means their measures are equal.

Set the measures 2x + 25 and 7x + 30 equal and solve for x.

7x + 30 = 2x + 25

5x = -5

x = -1

Now we use the value of x to find the measure of angle ADC.

m<ADC = 7x + 30 = 7(-1) + 30 = -7 + 30 = 23

Answer: 23°
