Step-by-step explanation:

TRIANGLES

______________________________

QUESTION:

IN A TRIANGLE ABC, /_A IS 70°

/_B IS 30°

THEN FIND ANGLE C

______________________________

SOLUTION:

BY ANGLE SUM PROPERTY.. MEASURE OF ANGLES OF TRIANGLE IS 180°

ANGLE A+B+C=180°

(70+30+C)° =180°

C= 80°

Answer 2

Step-by-step explanation:

The sum of the measure of all angles of a triangle = 180°

In ∆ABC,

Angle A = 70°

Angle B = 30°

Angle C = ?

Now,

Angle A + Angle B + Angle C = 180°

70° + 30° + Angle C = 180°

100° + Angle C = 180°

Angle C = 180° - 100°

Angle C = 80°

Therefore,

The measure of Angle C = 80°

( Note: I have written Angle C but please use symbol while writing in the book )

Hope it helps you !
