Question

please help with all 3!! will give brainliest!!

Answer 1

Answer:

11. 9. 4.

Step-by-step explanation:

Since BD bisects ABC, angle ABD = angle CBD.

(13x - 56) = (7x + 10)

6x = 66

x = 11.

Again for the next question BD bisects ABC.

(x + 15) = (4x - 12)

3x = 27

x = 9.

For the last question,

(9x + 9) = (12x - 3)

3x = 12

x = 4.
