A quadrilateral has angles that measure 115, 97, and 68. What is the measure of the missing angle?

Respuesta :

linandrew41

The sum of all the angles of any quadrilateral is 360 degrees

             115 + 97 + 58 + missing angle = 360

                   missing angle = 90 degrees

Hope that helps!

Answer:

90

Step-by-step explanation:

Since sum of all the angles of any quadrilateral is 360 degrees

115 + 97 + 58 + x = 360

Solve for x:

Add the numbers

270 + x = 360

Rearrange terms

x + 270 = 360

Subtract 270 from both sides of the equation

x + 270 - 270 = 360 - 270

Simplify

x = 90

Missing angle = 90
