Question

Help find x pls geometry help plssss

Answer 1

x = 28

Explanation:

From the figure attached,

In ΔABC and ΔADC,

AB ≅ AD [Given]

BC ≅ CD [Given]

AC ≅ AC [Reflexive property]

ΔABC ≅ ΔADC [SSS property of congruence]

Therefore, ∠ABC ≅ ∠ADC [CPCTC]

(4x + 13)° = (5x - 15)°

15 + 13 = 5x - 4x

x = 28
