Question

Which equation represents the

value of 0 in a triangle when all
oth er angle information is
known?

Answer 1

theta = 180 -(A +B)

Explanation:

The sum of the angles of a triangle is 180

theta + A + B = 180

solve for theta

Subtract ( A + B) from each side

theta +A+B -(A +B) = 180 -(A +B)

theta = 180 -(A +B)
