Explanation:
1.
angle ABD
2.
CB and BE
3.
"bisects" means it is cutting it in half.
so, angles 3 and 4 are both half of the main angle 94°.
94/2 = 47°
angle CBE = angle 4 = 47° = (3x - 7)°
3x - 7 = 47
3x = 54
x = 18
Answer: Number 1 Is also ∠ABC and it is a right triangle
Number 2 is CB and BE
Number 3 is 18
