Question

find the third angle of triangle angle A= 30 angle B= 70 angle c=

Answer 1

Answer:

Step-by-step explanation: The sum of all three angles in a triangle is 180.

A is 30

B is 70

A + B is 100

Therefore C is 180 - 100= 80

Answer 2

Answer: 80 degrees

Step-by-step explanation:

The sum of all angles of any triangle is 180 degrees .

we already know 2 angles

Their sum is 70 + 30 = 100

Therefore the angle left ,i.e., C = 180 - 100 = 80.
