Question

in ∆ ABC , |_ A = 70° ,|_ B = 50°
: |_ C = ?​

Answer 1

Answer:

60

Step-by-step explanation:

A+B+C=180

A+B=70+50=120

120+c= 180

=>c=180-120=60

mark me as brilliant if answer is correct

Answer 2

Answer:

Angle C = 60 degrees

Step-by-step explanation:

⇒ In Δ ABC,

Angle A = 70 degrees

Angle B= 50 degrees

⇒  Let angle C be x degrees.

We know that the ANGLE SUM PROPERTY of a triangle is 180 degrees.

⇒  So, we can put the equation as:

Angle A + Angle B + Angle C = 180 degrees.

SUBSTITUTING THE VALUES FOR ANGLE A AND ANGLE B,

Therefore, 70 degrees + 50 degrees + x degrees = 180 degrees.

⇒  120 degrees + x degrees = 180 degrees.

⇒  x degrees = 180 degrees - 120 degrees.

⇒  Therefore,

                    x = 60 degrees.

SO ,

ANS: ANGLE C OF Δ ABC IS 60 DEGREES.
