Question

Hello, please explain and solve this question​

Answer 1

Answer:

(b) and (c)

Step-by-step explanation:

In triangle ABD and triangle ACD,

AB = AC (given)

BD = CD (given)

AD = AD (common)

Therefore, ABD is congruent to ACD

angle BAD = angle CAD = x = 37º (cpct)

angle BDA = angle CDA = y = 70º (cpct)

x + y = 37 + 70 = 107º

(b) and (c) are correct.
