Three of the interior angles of a quadrilateral measure 51°, 120°, and 77°. What is the measure of the fourth interior angle?
The measures of the angles of a quadrilateral have sum 360∘. If x is the measure of the unknown angle, then: x + 51 + 120 + 77 = 360 x + 248 = 360 x + 248 − 248 = 360 − 248 x = 112 The angle measures 112°.
The measures of the angles of a quadrilateral have sum 360∘. If x is the measure of the unknown angle, then:
x + 51 + 120 + 77 = 360
x + 248 = 360
x + 248 − 248 = 360 − 248
x = 112
The angle measures 112°.
