Question

A triangle has 3 angle measures. 38 and 49, find the last measure

Answer 1

x = 93

Explanation:

The sum of the three angles of a triangle add to 180 degrees. Let the unknown angle be x

38+49+x = 180

Combine like terms

87 +x = 180

Subtract 87 from each side

87-87 +x = 180-87

x = 93
