Question

In triangle ABC,angle B=50, angle C=62 then find angle A=?​

Answer 1

Answer:

angle A is 68

Step-by-step explanation:

A+B+C=180(angle sum property)

A+50+62=180

A+112=180

therefore A= 180-112=68

Answer 2

Step-by-step explanation:

In triangle ABC,angle B=50, angle C=62

As from the rules of triangles,we know that the sum of all three angles made by the three sides of the triangle is equal to 180°

Implies that

angle B+angle C+angleA=180°

Now, let's assume that the angle A is x°

Implies that, angle A+angle B+angle C=180°

=62°+50°+x°=180°

=112°+x°=180°

=x°=180°-112°

=x°=68°

The value of x implies that the value of angle A is 68°.Now, verifying the answer,

angle A+angle B+angle C=180°

=68+62+50=180°

We see that the found answer satifies the rule,Thus the value of angle A=68°
