Question

triangle ABC is congruent DEF. If angle A = 30°, angle B = 45º then angle F is (in degrees)​

Answer 1

Answer:

triangle=180°

C=180-(45+30)

C=180-75

C=105°

Answer 2

Step-by-step explanation:

Given- triangle ABC is congruent DEF

So, angle A = angle D , angle B = angle E and angle C = angle F.

Now, In triangle ABC

angle A + angle B + angle C = 180°

30° + 45° + angle B =180°

angle B = 180°- 75°

angle B= 105°

So, angle F= 105° ( by CPCT )
