Question

Your given three angle measurements of 30, 70, and

Answer 1

Answer:

third angle be x = 80

Step-by-step explanation:

let the third angle be x

now,

In a triangle

A + B + C = 180

Similarly,

30 + 70 + x = 180

100 + x = 180

x = 180 - 100

x = 80

thus, three angle measurements of 30, 70, and 80
