Question

if triangle ABC is congruent to triangle d e f then the value of x is​

Answer 1

Answer:

Explanation:

Triangle ABC and triangle DEF are similar ,

Angle A = 47° = Angle D

Angle E = 83°= Angle B

C=?

In triangle ABC. A+B+C=180°. or. C= 180°-(A+B)

C= 180°-(47°+83°)

C=180°-130°

or. C = 50°. Answer.

Answer 2

Answer:

option C =80

Explanation:

given: angle B=65°

angle C=35°

angle B = angle E

angle C= angle F

therefore angle A = angle D

from triangle ABC

angle B + angle C + angle A = 180°

65°+35°+A= 180°

100° + A = 180°

A = 180°-100°

A= 80°
