Answer:
<em>41 degrees</em>
Step-by-step explanation:
<em>According to Angle Sum Property, the sum of the internal angles of a triangle is equal to 180 degrees.</em>
<em>Therefore,</em>
<em>52 + 87 + ? = 180</em>
<em>139 + ? = 180</em>
<em>? = 180 - 139</em>
<em>? = 41 degrees</em>
Answer:
A :) Sorry if it's wrong, I'm learning this too
Answer:
A. 121
Step-by-step explanation:
The sum of the exterior angles is 360°, so you have ...
z + (z +10) + (z -13) = 360
3z -3 = 360 . . . . . collect terms
z -1 = 120 . . . . . . . divide by 3
z = 121 . . . . . . . . . add 1
There is no graph, but it should be the one thats a parabola but its kind of wider
