Answer:
93
Step-by-step explanation:
A quadrilateral's 4 angles add to 360 degrees
70 + 92+<1 + 105 = 360
Combine like terms
267 + <1 = 360
Subtract 267 from each side
267-267 + <1 = 360-267
<1 = 93
OK it's simple...
The interior angles of ANY quadrilateral (a shape with 4 sides) add up to 360.
So all you have to do is add up the angles you already know (70+92+105=267) and subtract that from 360. (360-267).
