Question

d. In AABC, ZBAC = 70°, and
ZABC = 45°. What will
ZBCA be equal to?​

Answer 1

Answer:

65

Step-by-step explanation:

<abc+<bac+<bca=180

45+70+<bca=180

115+<bca=180

<bca=180-115

=65

Answer 2

Answer:

Here is the right answer to your question

Step-by-step explanation:

Given - ZBAC = 70° , ZABC = 45°

To Find - ZBCA

In ∆ABC,

Let ZBCA be x.

ZBAC + ZABC + ZBCA = 180° {Angle Sum Property}

=> 70° + 45° + x = 180°

=> 115° + x = 180°

=> x = 180° - 115°

=> x = 65°

Therefore, ZBCA = 65° .

This is the right answer.
